Reaction Steps

2-Chloro-N—((S)-1-hydroxypropan-2-yl)acetamide (700 mg, 4.64 mmol), potassium iodide (960 mg, 5.8 mmol) and cesium carbonate (1.9 g, 5.8 mmol) were added to a solution of 4-nitropyrazole (436 mg, 3.86 mmol) in acetonitrile (10 mL) then the mixture was heated to 160° C. for 30 min in a microwave reactor. The reaction mixture was combined with those from 13 other identical reactions, diluted with water then extracted four times with ethyl acetate. The combined organic layers were dried, concentrated in vacuo and purified by column chromatography (3% v/v MeOH/DCM) to afford (S)—N-(1-hydroxypropan-2-yl)-2-(4-nitro-1H-pyrazol-1-yl)acetamide (7.9 g, 64%) as a white solid.
