Participants

Reaction Steps

A solution of 24 (25 mg, 0.112 mmol) and 59 (9.86 mg, 0.112 mmol) in acetonitrile (4 mL) was added triethylamine (22.6 mg, 0.224 mmol). T3P (71.1 mg, 0.224 mmol) was added to the reaction mixture. The reaction was stirred overnight at rt, then diluted with ethyl acetate (25 mL). The organic layer was washed with water (25 mL) followed by brine solution (25 mL). The organic layer was dried over sodium sulphate, filtered and concentrated to get the crude, which was purified through flash chromatography by using 100-200 mesh silica gel. The compound was eluted at 2% methanol in chloroform as pale yellow colour solid compound 64. MS-ES+303.9; 1H NMR (400 MHz, DMSO-D6) 64: 11.37 (s, 1H), 10.65 (s, 1H), 8.41 (d, 1H), 8.06 (d, 1H), 7.90 (bs, 1H), 7.59 (d, 1H), 7.40 (m, 2H), 7.28 (bs, 1H), 2.42 (m, 2H), 2.30 (bs, 3H), 1.17 (t, 3H).
