Procedure

A solution of tert-butyl 5-(aminomethyl)-2-(2-chloro-3-quinolinyl)-1H-indole-1-carboxylate (7-4, 204 mg, 0.5 mmol, 1 equiv), HOAT (68 mg, 0.5 mmol, 1 equiv), triethylamine (101 mg, 1.0 mmol, 2 equiv), EDC (144 mg, 0.75 mmol, 1.5 equiv) and 1-BOC-piperidine4-carboxylic acid (126 mg, 0.55 mmol, 1.1 equiv) in DMF (5 mL) was stirred under ambient conditions for 18 hours. The reaction was concentrated, and the residue was partitioned between ethyl acetate and saturated aqueous NaHCO3 solution. The organic layer was washed with brine, dried over magnesium sulfate and concentrated to provide tert-butyl 5-[({[1-(tert-butoxycarbonyl)-4-piperidinyl]carbonyl}amino)methyl]-2-(2-chloro-3-quinolinyl)-1H-indole-1-carboxylate (7-5) as a white foam. 1H NMR (400 MHz, CDCl3) δ 8.25 (d, 1H, J=8 Hz), 8.16 (s, 1H), 8.05 (d, 1H, J=8 Hz), 7.85 (d, 1H, J=8 Hz), 7.76 (t, 1H, J=8 Hz), 7.59 (t, 1H, J=8 Hz), 7.49 (s, 1H), 7.28 (dd, 1H, J=8, 2 Hz), 6.61 (s, 1H), 4.48 (d, 2H, J=5 Hz), 4.12 (m, 2H), 2.72 (m, 2H), 2.26 (m, 1H), 1.84 (m, 2H), 1–0.65 (m, 2H), 1.42 (s, 91), 1.25 (s, 9H).
