実験手順
A solution of tert-butyl 4-(2-(4-carbamoylbenzyl)-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole-8-carboxamido)piperidine-1-carboxylate (28, 745 mg, 1.4 mmol) in 4 N HCl/dioxane (20.0 mL) was allowed to stir at room temperature for 2 h. The reaction mixture was then concentrated to give a tan solid which was triturated with ethyl ether to give 2-(4-carbamoylbenzyl)-N-(1-(4-cyanobenzyl)piperidin-4-yl)-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole-8-carboxamide as an off-white solid (700 mg, 99%); MS (ES) 432 (M+H).
