実験手順
To a solution of 1-(3,4-Dichloro-benzyl)-piperidin-4-one (3.1 g) in dichloromethane (50 ml) and acetic acid (0.69 ml) was added methylamine (6 ml of a 1M solution in tetrahydrofuran). The mixture was stirred for 5 minutes before the addition of sodium triacetoxyborohydride (3 g) and the resulting mixture stirred for 72 hours. Sodium bicarbonate solution (100 ml) added and the mixture stirred vigorously for 5 minutes before extraction of the product with dichloromethane (2×200 ml). The organics were separated, bulked and dried, (MgSO4). Purification by Biotage® 40S eluting 10%MeOH/0.5% 800 ammonia/dichloromethane gave the sub-title compound (1.8 g).
