실험 절차

A mixture of 1.80 g of methyl 7-(2-methoxyphenyl)-2-(methylsulfonyl)thieno[3,2-d]pyrimidine-6-carboxylate, 1.37 g of N-[4-(4-methylpiperazin-1-yl)-2-(propan-2-yloxy)phenyl]formamide and 4.44 g of 1-[N-(2-methylpropan-2-yl)-P,P-di(pyrrolidin-1-yl)phosphorimidoyl]pyrrolidine (BTPP) in 50 ml of anhydrous DMF is stirred at ambient temperature for 16 h. The mixture is then evaporated under vacuum at a temperature of 55° C., and the residue is diluted with ethyl acetate and water. The aqueous phase is extracted three times with ethyl acetate. The organic phases are washed with a saturated sodium chloride solution, dried over magnesium sulfate, filtered and concentrated under vacuum. The crude product is purified on 100 g of silica, elution being carried out with 0-2.5% of methanol containing 10% by volume of 28% aqueous ammonia solution in dichloromethane, so as to obtain 2.264 g of methyl 2-{formyl[4-(4-methylpiperazin-1-yl)-2-(propan-2-yloxy)phenyl]amino}-7-(2-methoxyphenyl)thieno[3,2-d]pyrimidine-6-carboxylate in the form of a brown solid.
