1,1-Dimethylethyl 2,6-dihydro-2-(methylsulfonyl)pyrrolo[3,4-c]pyrazole-5(4H)-carboxylate Use and Manufacturing

Intermediate 2 (3.5 g, 16.7 mmol) was dissolved in tetrahydrofuran (35 ml), and sodium hydride (1.0 g, 60percent, 25.4 mmol) was added at 0°C, followed by reaction for 30 min. Intermediate 2(3.5g, 16.7mmol) dissolved in tetrahydrofuran (35 ml) in, 0 °C adding of sodium hydride (1.0g, 25.4mmol, 60percent), 30 minutes reaction, adding methyl sulfonyl chloride (2.9g, 25.4mmol) reaction 1 hour. Adding water to the reaction solution (10 ml) in the quenching of the reaction, ethyl acetate (50mL × 2) extraction, the combined organic layer, anhydrous sodium sulfate drying, concentration, silica gel column chromatography for purification (petroleum ether/ethyl acetate (v/v)=1:1), to obtain white solid3a(2.1g, yield 44percent).2D (3.5 g, 16.7 mmol) was dissolved in tetrahydrofuran (35 mL)Cooled to 0 ° C, 60percent sodium hydride (1.0 g, 25.4 mmol) was added, After reaction for 30 minutes, methylsulfonyl chloride (2.9 g, 25.4 mmol) was added and reacted for 1 hour.The reaction mixture was quenched with water (10 mL) and extracted with ethyl acetate (50 mL x 2). The organic layers were combined and the organic layer was dried over anhydrous sodium sulfate and concentrated. The residue was purified by silica gel column chromatography (petroleum ether / Ethyl acetate (v / v) = 1: 1) to give 2E as a white solid (2.1 g, yield 44percent).
