Reaction Steps

(Chart D, Step 4): A dry round bottom flask is charged with 3-benzyl-11-(2-phenoxyethyl)-2,3,4,5-tetrahydro-1H-[1,4]diazepino[1,7-a]indole (317 mg, 0.80 mmol), ammonium formate (254 mg, 4.0 mmol), methanol (18 mL) and dichloromethane (3.2 mL). After the addition of 10% Pd/C (64 mg) the reaction is stirred at ambient temperature for two days. The reaction mixture is filtered through a pad of celite, and the catalyst is rinsed with methanol. The filtrates are combined and concentrated to 380 mg of a crude solid. This material is recrystallized from ethyl acetate/methanol/ethyl ether to afford 239 mg of 11-(2-phenoxyethyl)-2,3,4,5-tetrahydro-1H-[1,4]diazepino[1,7-a]indole as a white solid. IR (drift) 3026, 3015, 2998, 2983, 2948, 2910, 2869, 2806, 2781, 2752, 1468, 1451, 1245, 755, 746 cm−1.
