実験手順

To a solution of 1-(7-(3,4-dimethoxyphenylamino)thiazolo[5,4-d]pyrimidin-5-yl)piperidine-3-carboxylic acid (200 mg, 0.48 mmol) and methyl 5-aminopicolinate (73 mg, 0.48 mmol) in dichloromethane (30 mL) were added the solution of 1-methyl-1H-imidazole (158 mg, 1.92 mmol) and EDCI (368 mg, 1.92 mmol) in dichloromethane (10 mL), the reaction mixture was stirred at room temperature for 15 hours, the solvent was removed in vacuo and methanol (6 mL) was added and stirred for 30 minutes, the solid was collected by filtration and washed with methanol to afford methyl 5-(1-(7-(3,4-dimethoxyphenylamino)thiazolo[5,4-d]pyrimidin-5-yl)piperidine-3-carboxamido)picolinate (230 mg, 87.1%) as an orange solid. LC-MS: 550 [M+H]+, tR=1.58 min.
