الإجراء التجريبي

To a stirred solution of 59 (10 g, 31.2 mmol) in acetonitrile (20 mL) was added sodium bicarbonate (2.62 g, 31.2 mmol) and followed by mono methyl amine (40% in water) (30 mL, 3 vol) at 25-30° C. The reaction mixture was stirred for 3 hour 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, dried over Na2SO4 and concentrated under vacuum to afford crude 60 (7 g, yield: 82.3%) as a liquid
