Participants

Reaction Steps

To a solution of acid 24 (0.35 g, 1.3 mmol), DMAP (0.5 g, 4.1 mmol), N,O Dimethylhydroxyl amine HCl (0.5 g, 5.1 mmol) in DMF (15 ml) was added EDCl (0.5 g, 2.6 mmol) and the reaction was stirred at rt for 1 hr. The reaction was then poured into 2N HCl and extracted with EtOAc, The EtOAc was dried, concentrated, and the resulting solid was triturated with CH2Cl2 and collected by filtration to give 119 as a white solid (0.22 g, 55%): Mp=125-127° C.; 1NMR (DMSO-d6) δ 9.88 (br s, 1 H), 9.44 (s, 1 H), 7.65(d, 2 H, 8.6 Hz), 7.08 (br s, 1 H), 6.97 (d, 1 H, J=2.3 Hz), 6.88 (d, 2 H, J=8.6 Hz), 6.71 (d, 1 H, J=2.6 Hz), 3.59 (s, 3 H), 3.30 (s, 3 H): MS 312 [M−H]−
