Diisopropylamine → 4-(2-Fluorophenyl)-7-(isonicotinamido)-9H-pyrido[3,4-b]indole-1-carboxamide

Participants

Reaction Steps

A mixture of 7-(benzyloxycarbonylamino)-4-(2-fluorophenyl)-9H-pyrido[3,4-b]indole-1-carboxylic acid (214 mg, 0.470 mmol), ammonium chloride (101 mg, 1.880 mmol), N,N-diisopropylamine (0.394 mL, 2.255 mmol), BOP (270 mg, 0.611 mmol), N-methylmorpholine (0.201 mL, 1.833 mmol) in DMF (2 mL) was stirred at rt for 1 hr. To the reaction solution was added water (20 mL), and the precipitating product (213 mg, 0.422 mmol, 90% yield) was collected as a beige solid by suction filtration and dried over Drierite under vacuum.
