Participants

Reaction Steps

To 240 mg (1.02 mmol of 2,4-dichloro-5,6-dimethyl-thieno[2,3-d]pyrimidine in 50 ml of ethyl alcohol were added 220.20 mg (1.23 mmol) of 4-(4-morpholino)aniline and 130.90 mg (1.23 mmol) of aniline, and then the mixture was stirred under reflux. After completion of the reaction, the reaction solvent, ethyl alcohol, was evaporated under reduced pressure, and the residue was crystallized from ethyl alcohol and filtered, yielding 430 mg (quantitative) of 2-chloro-5,6-dimethyl-thieno[2,3-d]pyrimidin-4-yl-4-morpholin-4-yl-phenylamine. 220 mg (0.53 mmol) of the obtained product was dissolved in 20 ml of 1-butanol in a sealed tube, and 223 μl (1.59 mmol) of triethylamine and 45.9 mg of piperazine were added thereto, and the mixture was stirred at 120° C. After completion of the reaction, the resulting solid was filtered and the filtrate was concentrated under reduced pressure and then crystallized from ethyl acetate, yielding 30 mg (15% yield) of 5,6-dimethyl-2-piperazin-1-yl-thieno[2,3-d]pyrimidin-4-yl-4-morpholin-4-yl-phenylamine. To 9 mg (0.02 mmol) of the obtained compound and 5,6-dimethyl-2-piperazin-1-yl-thieno[2,3-d]pyrimidin-4-yl-4-morpholin-4-yl-phenylamine in 5 ml of dimethyl chloride were added 3.5 μl (0.02 mmol) of triethylamine and 4.1 mg (0.02 mmol) of picolinoyl chloride hydrochloride, and then the mixture was stirred at room temperature for 3 hours. After completion of the reaction, the reaction solvent, dimethyl chloride, was evaporated under reduced pressure, and the residue was crystallized from dimethyl chloride, thus obtaining 6 mg (30% yield) of the title product.
