A mixture of 4-(3-(benzyloxycarbonylamino)-2-methylphenyl)-7-(tetrahydrofuran-3-yloxy)-9H-pyrido[3,4-b]indole-1-carboxylic acid (0.195 g, 0.363 mmol), ammonium chloride (0.078 g, 1.451 mmol), N,N-diisopropylethylamine (0.304 mL, 1.741 mmol), BOP (0.209 g, 0.472 mmol), and N-methylmorpholine (0.156 mL, 1.415 mmol) in N,N-dimethylformamide (3 mL) was stirred at room temperature for 1.5 hr. To the reaction mixture was added water (30 mL), and the resulting mixture was stirred at room temperature for 30 min. The insoluble product (0.189 g, 0.352 mmol, 97% yield) was collected as a beige solid by suction filtration and dried over Drierite under vacuum.
