Participants

Reaction Steps

A solution of 4-(3-(benzyloxycarbonylamino)-2-methylphenyl)-6-morpholino-9H-pyrido[3,4-b]indole-1-carboxylic acid (0.1408 g, 0.262 mmol), ammonium chloride (0.056 g, 1.050 mmol), BOP (0.151 g, 0.341 mmol), DIPEA (0.220 mL, 1.260 mmol) and N-methylmorpholine (0.113 mL, 1.023 mmol) in DMF (2.187 mL) was stirred for 1 hr. Water (22 mL) was added, and the precipitate was filtered, washed with water, dried over Drierite to give the desired product (0.1277 g, 0.231 mmol, 88% yield) as a light tan solid.
