실험 절차

To a solution of (3S,5R)-3,5-dimethylmorpholine (1.15 g, 10 mmol) in DMF (15 mL) was added HATU (3.8 g, 10 mmol), DIPEA (2.6 g, 20 mmol), and 6-aminonicotinic acid (1.38 g, 10 mmol) at room temperature. The reaction mixture was stirred for 18 h. It was then filtered and the filtrate was purified with Combiflash (A: 1‰NH4HCO3/water, B: in acetonitrile) to afford 320a (650 mg, 27%) as a yellow solid. MS-ESI: [M+H]+ 236.1.
