YieldReaction ConditionsOperation in experiment
With sodium carbonate; In water; dimethyl sulfoxide; at 75℃; for 2h; Reference Example 155 A suspension of <strong>[228251-24-9]5-bromo-2-chloronicotinaldehyde</strong> (1.2 g), 3-methylpyrrolidine (928 mg) and sodium carbonate (1.16 g) in DMSO (40 ml) and water (20 ml) was stirred for 2 hours at 75C under a nitrogen atmosphere. After returning to room temperature, water was added thereto and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried over magnesium sulfate. The solvent was distilled off under reduced pressure, and then the resulting residue was separated and purified by silica gel column chromatography (hexane: ethyl acetate = 20: 1 ? hexane: ethyl acetate = 4: 1). The resulting solids were washed with hexane to give 5-bromo-2-(3-methylpyrrolidin-1-yl)nicotinaldehyde (761 mg) as yellow crystals. m.p. 72.0-73.0C. 1H-NMR (300 MHz, CDCl3) delta 1.13 (3H, d, J=6.6 Hz), 1.53-1.67 (1H, m), 2.07-2.16 (1H, m), 2.28-2.41 (1H, m), 3.17-3.24 (1H, m), 3.46-3.56 (2H, m), 3.61-3.70 (1H, m), 8.01 (1H, d, J=2.4 Hz), 8.31 (1H, d, J=2.4 Hz), 9.96 (1H, s).

YieldReaction ConditionsOperation in experiment
89% In water; at 205℃; for 0.5h;Microwave irradiation; A suspension of <strong>[1597-32-6]6-fluoropyridin-2-amine</strong> (448 mg, 4 mmol) and 3-methylpyrrolidine (408 mg, 4.8 mmol) in water (0.5 mL) was heated to 205 C. in a microwave oven for 30 minutes. The reaction mixture was purified by chromatography (silica gel, 200-300 mesh, petroleum ether:ethyl acetate=5:1) to give 6-(3-methylcyclopentyl)pyridin-2-amine (630 mg, 89%) as a colorless oil. LC-MS: [M+H]+, 178.2, tR=1.080 min.
