Reaction Steps

A mixture of 40 prepared above (120 mg, approx. 0.24 mmol), MeOH (1.1 mL) and 10% aq. HCl (2.4 mL) were stirred at room temperature for 1 h then poured onto saturated aq. NaHCO3/ethyl acetate. The aqueous phase was extracted with more ethyl acetate and the combined organic extracts dried (MgSO4) and concentrated to give pure product 41 (40.8 mg, 44% over 3 steps from 26); 1H NMR (400 MHz, CDCl3) δ 6.40 (dd, J=3.4, 1.6 Hz, 1H), 6.76 (t, J=4.8 Hz, 1H), 7.21 (m, 2H), 7.32 (dt, J=7.8 Hz, 1.8 Hz, 1H), 7.39 (dt, J=7.8, 1.8 Hz, 1H), 7.46 (dd, J=7.5, 1.8 Hz, 1H), 8.04 (d, J=2.0 Hz, 1H), 8.30 (d, J=4.8 Hz, 2H), 8.37 (d, J=2.0 Hz, 1H), 10.26 (bs, NH).
