Versuchsvorschrift

To a solution of 2-(benzyloxycarbonyl)-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole-8-carboxylic acid (3, 0.5 g, 1.4 mmol) in DMF (10 mL), HATU (0.65 g, 1.7 mmol), 4-amino-1-(4-cyanobenzyl)piperidine dihydrochloride (0.41 g, 1.4 mmol) and triethylamine (1.05 mL, 0.76 g, 7.5 mmol) were added. The resulting reaction mixture was allowed to stir at room temperature overnight, poured into saturated sodium bicarbonate solution (75 mL) and extracted with EtOAc (3×50 mL). The combined organic layers were washed with water (2×30 mL), brine (1×30 mL), dried (MgSO4), filtered and concentrated to give a tan solid. Column chromatography (neat DCM→5% MeOH/DCM) provided benzyl 8-(1-(4-cyanobenzyl)piperidin-4-ylcarbamoyl)-3,4-dihydro-1H-pyrido[4,3-b]indole-2(5H)-carboxylate (4a in Scheme 1(b)) as a white solid upon trituration with ethyl ether (0.55 g, 70%). 1H NMR (DMSO-d6, 300 MHZ) 11.14 (br s, 1H), 8.04 (d, J=8.0 Hz, 1H), 8.00 (s, 1H), 7.79 (d, J=8.0 Hz, 2H), 7.59 (d, J=8.5 Hz, 1H), 7.51 (d, J=7.7 Hz, 2H), 7.39-7.27 (m, 6H), 5.14 (s, 2H), 4.67 (br s, 2H), 3.80 (br s, 3H), 3.57 (s, 2H), 2.82 (br s, 4H), 2.08 (t, J=11.0 Hz, 2H), 1.80 (d, J=11.3 Hz, 2H), 1.61 (q, J=10.7 Hz, 2H) ppm; MS (ES) 548 (M+H).
