实验过程
To a stirred solution of 74 (2 g, 5.7 mmol) in acetonitrile (10 mL) was added sodium bicarbonate (0.48 g, 5.74 mmol) and followed by dimethyl amine (40% in water) (10 mL, 88.8 mmol) at 25-30° C. The reaction mixture was stirred for 3 hours at 25-30° C.; the reaction was monitored by TLC. The solid obtained in the reaction mixture was filtered under vacuum. The solvent was concentrated, diluted with ethyl acetate/water and stirred for 15 minutes at 25-30° C. The aqueous and organic layers were separated, and the aqueous layer was extracted with ethyl acetate (2×10 mL). The combined organic layers were washed with brine solution. The organic layer was dried over Na2SO4 and concentrated under vacuum to afford crude 75 (1.49 g, yield: 83%) as a liquid.
