실험 절차

0.600 g (1.95 mmol) of 3-(2-chloro-6,7-dihydrothieno[3,2-d]pyrimidin-4-ylamino)benzoic acid (I), 0.741 g (1.95 mmol) of O-(7-azabenzotriazol-1-yl-)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU), and 0.680 mL (3.90 mmol) of is diisopropylethylamine are placed in 10 mL of dimethylsulfoxide, then stirred for 0.5 hours at ambient temperature. 0.220 mL (1.95 mmol) of methylpiperazine (II) is added, then the mixture is stirred for 3 hours at ambient temperature. Then the reaction mixture is concentrated by evaporation and the residue is combined with water. Any precipitate formed is suction filtered and dried. The crude product is purified by chromatography through a 50 g silica cartridge with ethyl acetate/methanol 8:2. 0.250 g of product III (33%) is obtained.
