実験手順
To a tetrahydrofuran suspension of 480 mg of 60% sodium hydride, 2 ml of ethyl formate and 1.0 g of ethyl methoxyacetate were added under nitrogen atmosphere, and the mixture was stirred for 16 hours at room temperature. In succession, adding 1.0 g of 3-amino-4(4-phenylthiophenyl)pyrazole, the solution was stirred for 4 hours in reflux. After allowing to cool, water was added and the solution was neutralized with 10% hydrochloric acid. Removing water, ethyl acetate was added, and insoluble matter was filtered. The filtrate was washed in ethyl acetate and ether and dried, and the title compound was obtained (100 mg, 8%).
