Procedure

A mixture of EXAMPLE 98C in dichloromethane (5 mL) and TFA (5 mL) was stirred at room temperature overnight and concentrated. The concentrate was partitioned between water (50 mL) and ethyl acetate (200 mL), and the organic phase was washed with brine and dried (Na2SO4), filtered and concentrated. 1H NMR (300 MHz, DMSO-d6) δ 12.88 (m, 1H), 11.00 (s, 1H), 8.22 (m, 1H), 7.85 (m, 3H), 7.86 (m, 1H), 7.73 (d, 1H), 7.32-7.55 (m, 5H), 7.08 (m, 2H), 6.92 (d, 1H), 4.25 (m, 4H), 3.36 (t, 2H), 2.24 (t, 2H), 2.10 (s, 3H), 1.26 (t, 3H).
