Reaction Steps

The compound (150 mg, 0.32 mmol) of example 71 was dissolved in dichloromethane (20 ml), added with triethylamine (0.5 ml) and morpholine (40 mg, 0.46 mmol), followed by stirring for 12 h. The reaction mixture was washed orderly with water (10 ml) and saturated saline. The organic phase was dried with anhydrous Na2SO4, and concentrated under reduced pressure to give an oil, which was passed through a silica gel column to obtain the title compound (60 mg, yield: 39%). 1H NMR (CDCl3) δ: 11.20 (1H, br), 9.21 (1H, d), 8.17 (1H, dd), 7.15 (1H, d), 4.30 (2H, t), 3.75-3.64 (10H, br), 3.52 (1H, m), 2.03 (2H, m), 1.30 (6H, d), 1.16 (3H, t).
