실험 절차
Trifluoroacetic acid (2 mL) was added to a stirred solution of tert-butyl 3-(methylcarbamoyl)spiro[indene-1,4′-piperidine]-1′-carboxylate (C5) (0.45 g, 1.30 mmol) in dichloromethane (5 mL) and the solution was stirred at room temperature for 1 h. The solvent was removed under reduced pressure and dried under high vacuum for 18 h to provide N-methylspiro[indene-1,4′-piperidine]-3-carboxamide (C6) as an oil (0.46 g). LC/MS (10-90% over 3 min with 0.9% FA) m/z 243 (M+1), Rt 1.2 minutes.
