YieldReaction ConditionsOperation in experiment
73% [Referential Example 16]; 1-(4-Methoxy-2-pyridyl)ethanone ; [] In an argon atmosphere, 0.93M methylmagnesium bromide in tetrahydrofuran (13.8 mL) was added dropwise to 4-methoxypyridine-2-carbonitrile (1.56 g) in tetrahydrofuran (31 mL) at -78C, followed by stirring for 15 minutes. Subsequently, the reaction mixture was stirred at 0C for 15 minutes, and then at room temperature for 5 hours. Water was added dropwise to the reaction mixture. The resultant mixture was partitioned between water and ethyl acetate. The organic layer was dried over sodium sulfate anhydrate, followed by filtration. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane - ethyl acetate), to thereby give the title compound as a solid substance (1.30 g, 73%) .1H-NMR(400MHz,CDCl3) δ: 2.72(3H,s), 3.91(3H,s), 6.97-6.99(1H,m), 7.57-7.58(1H,m), 8.48-8.50(1H,m).

YieldReaction ConditionsOperation in experiment
3.60 g (60%) With MeMgI; In benzene; 2-Acetyl-4-methoxypyridine: To a solution of 4-methoxy-2-pyridinecarbonitrile (5.35 g, 38.6 mmol) in benzene (50 ml) and ether (50 ml) cooled to 0 C. was added dropwise over 20 min a 2M slution of MeMgI in ether (23 ml, 46.3 mmol). After 0.5 h, the mixture was allowed to warm to ambient temperature, and stirring continued for 2 h. The mixture was cooled to 0 C. and 2M aqueous HCI (100 ml) added. The mixture was made basic with saturated aqueous sodium bicarbonate (~80 ml) and the organic layer separated and dried (MgSO4). After removal of solvent, the residue was purified by flash chromatography eluding with ethyl acetate/hexane (1:5) to afford 3.60 g (60%) of 2-acetyl-4-methoxypyridine. 1H-NMR (CDCl3) δ: 8.49 (1 H, d, J=5.5 Hz), 7.58 (1 H, d, J=2.6 Hz), 6.98 (1 H, dd, J=2.6, 5.5 Hz), 3.91 (3H, s), 2.72 (3 H, s)
