Procedure

To a solution of tert-butyl 4-(2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole-8-carboxamido)piperidine-1-carboxylate (0.745 g, 1.9 mmol) in DMF (10 mL), 4-bromomethylbenzamide (0.44 g, 2.1 mmol) and TEA (1.2 mL, 0.857 g, 8.5 mmol) were added. The resulting dark yellow reaction mixture was allowed to stir at room temperature under N2 atmosphere overnight and then poured into saturated sodium bicarbonate solution (100 mL). The resulting precipitate was collected and dried under vacuum overnight to provide tert-butyl 4-(2-(4-carbamoylbenzyl)-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole-8-carboxamido)piperidine-1-carboxylate (28 in Scheme 1(m)) as a white solid (0.75 g, 75%). 1H NMR (DMSO-d6, 300 MHZ) 10.80 (s, 1H), 7.86-7.79 (m, 4H), 7.55 (d, J=8.5 Hz, 1H), 7.45 (d, J=8.3 Hz, 3H), 7.26 (d, J=8.5 Hz, 2H), 4.00-3.88 (m, 3H), 3.82 (s, 2H), 3.65 (s, 2H), 2.92-2.80 (m, 6H), 1.80 (d, J=9.9 Hz, 2H), 1.54-1.47 (m, 2H), 1.43 (s, 9H) ppm; MS (ES) 532 (M+H).
