実験手順

A mixture composed of 4-amino-2-[(4-methoxy-3,5-dimethylpyridin-2-yl)methyl]-7,8-dihydro-2H-6-thia-1,2,3,5-tetraazaacenaphthylene-7-carboxylic acid of Example 8 (80 mg), cyclopropylamine (0.029 mL), 1-hydroxybenzotriazole monohydrate (32 mg), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (80 mg) and dehydrated N,N-dimethylformamide (10 mL) was stirred at room temperature for 16 hours. The reaction mixture was concentrated under reduced pressure. The resulting residue was diluted with ethyl acetate and sequentially washed with a saturated sodium bicarbonate solution and brine. The organic layer was dried over anhydrous magnesium sulfate and filtered. Then, the filtrate was concentrated under reduced pressure. The resulting residue was purified by NH silica gel column chromatography (dichloromethane-methanol) to obtain the title compound (30 mg, 34%) as a solid.
