YieldReaction ConditionsOperation in experiment
34% Step 1 : Potassium tert-butoxide (4.49 mL, IM in THF) was added over about5 minutes to (methoxymethyl) triphenylphosphonium chloride (1.42 g, 4.15 mmol) suspended in anhydrous THF (25 mL) at O0C. The resulting suspension was stirred at about this temperature for about 45 minutes at which time, tert-butyl 2-benzyl-4-oxopiperidine-l- <n="111"/>carboxylate (1.Og, 3.46 mmol) dissolved in THF (5 niL) was added. The reaction mixture was allowed to warm to ambient and stir for another 6h. The reaction was quenched by the addition of ammonium chloride solution and then taken up in EtOAc. After washing twice with water and once with brine, the organic portion was dried over magnesium sulfate, filtered and concentrated. The resulting semi-solid residue was purified via silica gel chromatography to give (Z)-tert-butyl 2-benzyl-4-(methoxymethylene)piperidine-l- carboxylate (375 mg, 34%). LCMS (APCI+) m/z 218.1 [M+H]+; Rt = 4.51 min.

The solution was stirred at -10 C. for 2 h and then allowed to reach room temperature over 16 h. To the reaction mixture was added H2O (400 mL) and the solution was stirred for 20 min and then extracted with DEE (×3) and EtOAc (×3). The combined organic phases were dried over Na2SO4 and evaporated. The residue was purified by column chromatography using EtOAc/heptane (10-60% gradient EtOAc) to yield tert-butyl 2-benzyl-4-cyanopiperidine-1-carboxylate (11.85 g, 76%). 1H NMR (600 MHz, cdcl3) delta 1.38-1.46 (m, 9H), 1.63-2.14 (m, 4H), 2.62-3.33 (m, 4H), 4.17 (m, 1H), 4.48 (m, 1H), 7.11-7.41 (m, 5H); MS m/z 301 (M+H)+.

YieldReaction ConditionsOperation in experiment
To a solution of 2-benzylpiperidin-4-one (BETAPHARMA, 0.868 g, 3 mmol) in anhydrous THF (10 mL) was added LiHMDS (1M solution in THF, 6 mL) dropwise at -78 C. After addition, the mixture was allowed to warm to -30 C. and stirred for 20 min. The mixture was cooled to -78 C. again and 1,1,1-trifluoro-N-phenyl-N-(trifluoromethylsulfonyl)methanesulfonamide (2.144 g, 6 mmol) was added. The mixture was allowed to warm to ambient temperature and stirred for 2 h. The solvent was removed in vacuo and the residue was purified by flash column chromatography on silica gel (eluting with 2% EtOAc in petroleum ether) to give tert-butyl 6-benzyl-4-(((trifluoromethyl)sulfonyl)oxy)-5,6-dihydropyridine-1(2H)-carboxylate as an oil (0.72 g, crude), which was used in the next step without further purification. TLC (eluting with 10% EtOAc/PE) Rf=0.5.

YieldReaction ConditionsOperation in experiment
100% Into a 5-L round-bottom flask purged and maintained with an inert atmosphere of nitrogen was placed <strong>[193480-28-3]tert-butyl 2-benzyl-4-oxopiperidine-1-carboxylate</strong> (5 g, 17.28 mmol, 1.00 equiv), methanol (4 L), acetic acid (2.076 g, 34.57 mmol, 2.00 equiv) and HCOONH4 (43.599 g). The resulting solution was stirred for 0.5 h at room temperature. Then NaBH3CN (2.180 g, 34.69 mmol, 2.01 equiv) was added by batchwise. The resulting solution was stirred overnight at room temperature. The resulting mixture was concentrated under vacuum. The resulting solution was diluted with 200 mL of EA. The resulting mixture was washed with 4x100 mL of brine (sat.). The organic phase was collected and concentrated under vacuum. The solid was dried in an oven under reduced pressure. This resulted in 5 g (100%) of tert-butyl 4-amino-2-benzylpiperidine-1- carboxylate as light yellow oil. LCMS (method C, ESI): RT =0.89 min, m/z =235.0 [M- 56+H]+.
