実験手順

0.462 g (3.7 mmol) of 1-methyl-1H-pyrrol-2-carboxylic acid (VII), 1.4 g (9.7 mmol) of O-(7-azabenzotriazol-1-yl-)-N,N,N′,N′-tetramethyluroniumhexafluorophosphate (HATU), and 0.640 mL (3.7 mmol) of diisopropylethylamine are placed in 10 mL of dimethylsulfoxide, then stirred for 0.1 hours at ambient temperature. 0.814 g (3.0 mmol) of (2-chloro-6,7-dihydrothieno[3,2-d]pyrimidin-4-yl)piperidin-3-ylamine hydrochloride (VI) and 3.7 mmol of diisopropylethylamine are added, then the mixture is stirred for 16 hours at ambient temperature. Then the reaction mixture is suction filtered through Alox, and the mother liquor is concentrated by evaporation. The residue is combined with 1 N sodium hydroxide solution and extracted with dichloromethane. The organic phase is separated off using a phase separator and evaporated to dryness. The crude product is purified by chromatography through a Biotage silica gel cartridge 40s with petroleum ether/ethyl acetate 1:1. 0.970 g of product VIII (85%) is obtained.
