실험 절차

To a solution of N-[2,4-dichloro-3-(2-methylsulfanyl-7-oxo-7,8-dihydro-pyrido[2,3-d]pyrimidin-6-yl)-phenyl]-3-trifluoromethyl-benzamide (1.14 g, 2.17 mmol) in DMF (35 mL) is slowly added NaH (117.2 mg, 60%, 2.93 mmol) with stirring for 30 minutes a 0° C. Iodomethane (369 mg, 2.60 mmol) is added to above solution with stirring for 40 minutes at 0° C. The solvents are evaporated and diluted with EtOAc and washed with saturated K2CO3, brine and water. The organic layer is dried, filtered and concentrated to give crude product, which is purified by flash silica gel column, eluting with CH2Cl2 (100%) gradient to CH2Cl2/MeOH(NH3, 2N)(93/7), to give the title intermediate as a solid (1.14 g, 98.0%).
