실험 절차

To a solution of (R)-tert-butyl 1-(4-(2-cyanobenzyl)-6-methyl-5-oxo-4,5-dihydro-1,2,4-triazin-3-yl)piperidin-3-ylcarbamate (7, 13 mg) in dichloromethane (0.5 mL) was added HCl in methanol (20%) (1 mL) and the mixture was stirred at RT for 2 h. The mixture was carefully neutralized with NaHCO3 (aq, saturated), and extracted with CH2Cl2 (50 mL×3). The combined extracts were dried over Na2SO4 and concentrated to give the crude product. This was purified by column chromatography on silica gel, eluted with 92:6:2 dichloromethane-methanol-ammonia to provide (R)-2-((3-(3-aminopiperidin-1-yl)-6-methyl-5-oxo-1,2,4-triazin-4(5H)-yl)methyl)benzonitrile (8). MS: m/z, 325 (100%, M+1).
