실험 절차

To a mixture of cyclopropanecarboxylic acid (180 mg, 2.0 mmol), HATU (570 mg, 1.5 mmol) and DIPEA (390 mg, 3.0 mmol) in DCM (8 mL) was added 3-amino-5-bromo-1-methylpyridin-2(1H)-one (230 mg, 1.12 mmol). The reaction mixture was stirred at 25° C. for 5 hours. The resulting mixture was evaporated under reduced pressure and the residue was purified on a silica-gel column chromatography eluting with 20:1 DCM/methanol to afford the 102a (220 mg, 72%). MS-ESI: [M+H]+ 270.1
