Reaction Steps

A mixture of compound 37-b (15 g, 71 mmol), compound 37-h (12.2 g, 77.8 mmol), triethylamine (21.4 g, 212 mmol) in methanol (200 mL) was stirred overnight at room temperature. The residue obtained from removal of the solvent was purified by flash chromatography (DCM) to afford compound 37-i (7.5 g, 39%) as a yellow solid. 1H NMR (300 MHz, CDCl3) δ 8.668-8.649 (m, 1H), 8.428-8.395 (m, 1H), 8.257 (s, 1H), 7.937-7.880 (m, 1H), 7.517-7.471 (m, 1H), 0.285 (s, 9H). LC-MS (ESI): 270 [M+H]+
