実験手順

To a solution of 50% aqueous dimethyl amine (0.13 g) in ethanol (5 mL) were added 2,4-dichlorothieno[3,4-d]pyrimidine (0.20 g) and triethylamine (0.10 g) at room temperature, and the mixture was stirred for 2 h. The reaction mixture was concentrated under reduced pressure and diluted with chloroform and water, and then the aqueous layer was extracted with chloroform. The organic layer was washed with 1 M hydrochloric acid and saturated brine, then the organic layer was dried with anhydrous magnesium sulfate, then the desiccant was removed by filtration, the filtrate was concentrated under reduced pressure, and the residue was crystallized with diethyl ether to obtain 2-chloro-N,N-dimethylthieno[3,4-d]pyrimidin-4-amine (0.16 g). (2) To a mixture of 2-chloro-N,N-dimethylthieno[3,4-d]pyrimidin-4-amine (0.156 g), Pd2(dba)3 (0.033 g), (±)-BINAP (0.068 g), 1-((3R,4R)-3-amino-4-hydroxypyrrolidin-1-yl)-2-(4-trifluoromethoxyphenyl)ethanone (0.27 g), and 1,4-dioxane (8 mL) was added sodium t-butoxide (0.21 g) under nitrogen atmosphere, and the mixture was stirred at room temperature for 12 h. The reaction mixture was diluted with ethyl acetate and water, the interlayer was removed by Celite filtration, and the organic layer was washed with saturated brine. The organic layer was dried with anhydrous magnesium sulfate, then the desiccant was removed by filtration, the filtrate was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (silica gel, chloroform/methanol, and NH silica gel, ethyl acetate) to obtain light yellow amorphous 1-((3R,4R)-3-(4-dimethylaminothieno[3,4-d]pyrimidin-2-ylamino)-4-hydroxypyrrolidin-1-yl)-2-(4-trifluoromethoxyphenyl)ethanone (0.037 g).
