실험 절차

To a solution of (R)-tert-butyl 1-(4-(2-chloro-5-fluorobenzyl)-6-methyl-5-oxo-4,5-dihydro-1,2,4-triazin-3-yl)piperidin-3-ylcarbamate (31, 44 mg) in dichloromethane (1 mL) was added TFA (0.4 mL), and the mixture was stirred at RT for 1.5 h. The mixture was carefully neutralized with NaHCO3 (aq, saturated), and extracted with CH2Cl2 (10 mL×3). The combined extracts were dried over Na2SO4 and concentrated to give (R)-3-(3-aminopiperidin-1-yl)-4-(2-chloro-5-fluorobenzyl)-6-methyl-1,2,4-triazin-5(4H)-one (32). MS: m/z, 352 (100%, M+1), 354 (33%).
