Participants

Reaction Steps

[7-hydroxy-6-methoxy-3-(3,4,5-trimethoxy-benzoyl)-benzofuran-2-ylamino]acetic acid (30 mg, 0.07 mmol) was dissolved in dry methanol (5 mL) and trimethylsilyl chloride (100 μL) was added to it. The reaction was stirred at room temperature for 6 hours (monitored by tlc). Solvent was distilled under vacuum and the crude was purified over silica gel plate to afford the title compound as yellow solid (23 mg, 79%); 1H NMR (300 MHz, CDCl3) δ 9.11(b, 1H, NH), 6.97(s, 2H, benzoyl Hs), 6.62(d, 1H, J=8.56 Hz), 6.51(d, 1H, J=8.49 Hz), 4.42(d, 1H, J=6.09 Hz), 3.91(s, 3H, OMe), 3.86(s, 3H, OMe), 3.84(s, 6H, 2×OMe), 3.81(s, 3H, OMe).
