YieldReaction ConditionsOperation in experiment
With lithium hexamethyldisilazane; In tetrahydrofuran; at -78 - 20℃; for 1h; <strong>[30413-58-2]2-ethynyl-6-methylpyridine</strong> (0.040 g, 0.34 mmol) was dissolved in THF (2.5 mL) and the solution was cooled to-78 C. Lithium bis (trimethylsilyl) amide (0.69 mL of a 1.0 M solution in THF, 2.0 eq. ) was added and the solution was stirred for 0. 5h at that temperature before 2-methylpropanal (0.050 g, 0.063 mL, 0.69 mmol, 2.0 eq. ) was added. After that time the temperature of the reaction mixture was allowed to reach room temperature and after stirring for 0. 5h at that temperature, the mixture was passed through a SCX column, 5 g, while eluting with THF and MeOH, respectively. To elute the compound, the column was finally eluted with a saturated solution of ammonia in MeOH. This gave 0.080 g crude product that was used for the preparation of compound 35 (see below) without further purification.

["C]-Mel is introduced via a slow stream of helium and when addition is completed the reaction mixture is heated to 120C for 10 min. Product purification is accomplished by reversed phase HPLC using a C-18 U-BONDAPAK column (7. 8X300MM) and a mobile phase consisting of CH3CN/0. 1% H3PO4 (70/30) at a flow rate of 5 ML/MIN. The retention time of the desired product is between 6 and 7 min. 3-(6-METHYL-PYRIDIN-2-YLETHYNYL)-CYCLOHEX-2-ENONE O-["C-METHYL]-OXIME is formulated in a solution containing polysorbatum (2%), ethanol (10%) and saline (0.9%).

After that time the solution is diluted with ethyl acetate (500 ml) and washed with sat aq. NAHCO3 (1 X 150 ML). The water phase is extracted with ethyl acetate (1 X 150 ML) and the combined organic phases are dried over NA2SO4, filtered and concentrated in vacuo. The residue (1.88 g) is purified on column chromatography (silica gel, eluent hexane/ethyl acetate 3: 1 V/V) and the fractions containing the desired compound are collected and concentrated in vacuo to yield 1.05 g (yield = 82 %) of the title compound as a light yellow oil. b) 3- (6-Methyl-pyridin-2-ylethynyl)-cyclohex-2-enone oxime A solution of 3- (6-methyl-pyridin-2-ylethynyl)-cyclohex-2-enone (422 mg, 2 MMOL) and hydroxylamine hydrochloride (278 mg, 4 MMOL) in pyridine (20 ml) is stirred for 17 h at RT. After that time the solvent is evaporated in vacuo. The residue is dissolved in ethyl acetate (300 ml) and washed with sat NAHCO3 (1 X 50 ML). The water phase is extracted with ethyl acetate (1 X 50 ML). The combined organic phases are dried over NA2SO4, filtered and concentrated in vacuo.

YieldReaction ConditionsOperation in experiment
With copper(l) iodide; In water; for 2h;Sonographic reaction; A mixture of <strong>[30413-58-2]2-ethynyl-6-methyl-pyridine</strong> (0.08 g, 0.7 mmol), 1-Boc-4-piperidinecarboxaldehyde (0.1 g, 0.47 mmol), CuI (0.001 g, 0.11 mmol) and 33% w/w aqueous dimethylamine (0.077 mL, 0.56 mmol) in water (3 mL) was sonicated for 2 h in a laboratory ultrasonic bath. Afterwards, it was extracted with EtOAc and the combined organic layers were washed with brine, dried on Na2SO4 and evaporated to dryness in vacuo to give a crude, which was purified by automated flash liquid chromatography (Horizon-Biotage) eluting with EtOAc-Petroleum Ether 1:1 affording the title product (0.11 g).1H-NMR (CDCl3, delta): 1.25-1.48 (m, 2H), 1.51 (s, 9H), 1.65-1.73 (m, 1H), 2.05-2.11 (m, 2H), 2.23-2.40 (br, 6H), 2.66 (s, 3H), 2.69-2.77 (m, 2H), 3.21-3.39 (m, 1H), 4.09-4.21 (m, 2H), 7.09-7.11 (m, 1H), 7.27-7.30 (m, 1H), 7.53-7.56 (m, 1H).MS: [M+H]+=358.6

YieldReaction ConditionsOperation in experiment
A mixture of zinc trifluoromethanesulfonate (0.07 g, 0.19 mmol) and triethylamine (0.065 mL, 0.47 mmol) in anhydrous toluene (5 mL) was stirred at room temperature under nitrogen atmosphere. After 1 h, <strong>[30413-58-2]2-ethynyl-6-methyl-pyridine</strong> (0.13 g, 1.13 mmol) prepared as described in WO200544267 was added and after 15 min was dropped a solution of 1-Boc-4-piperidinecarboxaldehyde (0.2 g, 0.938 mmol) in toluene (1 mL): the resulting mixture was heated at 100 C. for 6 h. Afterwards, it was cooled to r.t., diluted with water and extracted with EtOAc. The combined organic layers were washed with brine, dried on Na2SO4 and evaporated to dryness in vacuo to give a crude, which was purified twice by automated flash liquid chromatography (Horizon-Biotage) eluting with CHCl3-MeOH 98-2 affording the title product (0.13 g) as a brown oil.1H-NMR (CDCl3, delta): 1.27-1.5 (m, 12H), 1.85-2.01 (m, 3H), 2.63 (s, 3H), 2.65-2.82 (m, 2H) 4.15-4.31 (m, 2H), 4.44-4.49 (m, 1H), 7.15-7.18 (m, 1H), 7.27-7.30 (m, 1H), 7.61-7.65 (m, 1H).MS: [M+H]+=331.6
