48% | With potassium carbonate; In acetonitrile; at 85℃; | Add acetonitrile (41 mL) to a mixture of 5-methyi-3-nitro-IH-pyrazole (1.1 g, 8.2mmnoi), potassium carbonate (2.3 g, 2.0 eq). and (R)-I-chioro-2-propanoi (092 mL, 1.3eq). Stir at 85 ?C overnighi. Cool to ri. Filter and rinse the solids with EtOAc, Concentrate the filtrate in vacuo to provide a residue. Subject the residue to normal phase chromatography, eluting with 50% EtOAc in hexanes, to give the title compound as a white solid (0.74 g, 48%). MS (ES) in/i 186 (M+F1). |
