Sodium borohydride → (4-aminomethyl-3-methylphenyl)-(5H,11H-benzo[e]pyrrolo[1,2-a][1,4]diazepin-10-yl)methanone

Participants

Reaction Steps

Following a similar procedure as described for Example F2, 4-(5H,11H-benzo[e]pyrrolo[1,2-a][1,4]diazepine-10-carbonyl)-2-methylbenzonitrile from Example G1 (1.5 g, 4.6 mmol) was treated with cobalt (II) chloride (2.2 g, 9.2 mmol) and sodium borohydride (1.75 g, 46 mmol) to afford a pale yellow solid, yield 680 mg, 44%.
