Procedure

1.25 g 2,4-dichloro-6,7-dihydro-thieno[3,2-d]pyrimidine are placed in 5 ml dimethylformamide, first 1.05 ml diisopropylethylamine, then 0.960 g 3-morpholin-4-ylmethyl-phenylamine (J. Med. Chem. 1990, 33, 327) are added. The reaction mixture is sf 20 hours at 60° C., then after cooling evaporated down. The residue is extracted with dichloromethane and water, the organic phase is dried and evaporated to dryness. The residue is crystallised with petroleum ether/ethyl acetate. 1.28 g of the product are obtained as a powder.
