Versuchsvorschrift

A mixture of 527 mg of N-[4-(1-methylpiperidin-4-yl)-2-(propan-2-yloxy)phenyl]formamide and 953 mg of 1-[N-(2-methylpropan-2-yl)-P,P-di(pyrrolidin-1-yl)phosphorimidoyl]-pyrrolidine (BTPP) in 10 ml of anhydrous DMF is stirred at ambient temperature for 30 min, and then a solution of 577 mg of methyl 7-(2-methoxyphenyl)-2-(methylsulfonyl)thieno[3,2-d]pyrimidine-6-carboxylate in 15 ml of anhydrous DMF is slowly added. The mixture is stirred at ambient temperature for 48 h, and then diluted with ethyl acetate and washed three times with water. The organic phase is dried over magnesium sulfate, filtered and concentrated under vacuum. The crude product is purified on 80 g of silica, elution being carried out with 5-10% of methanol in dichloromethane, so as to obtain 615 mg of methyl 7-(2-methoxyphenyl)-2-{[4-(1-methylpiperidin-4-yl)-2-(propan-2-yloxy)phenyl]amino}thieno[3,2-d]pyrimidine-6-carboxylate in the form of a yellow solid. The crude product is diluted with 600 ml of 7N ammoniacal methanol and the solution is stirred at ambient temperature for 48 h, and then concentrated under vacuum. The residue is solubilized with 100 ml of hot ethyl acetate and the solution is left to cool in order to obtain a suspension. The suspension is cooled in an ice bath and filtered. The solid is washed with ethyl ether and dried under vacuum, so as to obtain 477 mg of 7-(2-methoxyphenyl)-2-{[4-(1-methylpiperidin-4-yl)-2-(propan-2-yloxy)phenyl]amino}thieno[3,2-d]pyrimidine-6-carboxamide in the form of a yellow solid.
