Reaction Steps

A solution of 2-chloro-3-fluoro-pyridine (1.3 g, 10.0 mmol), 1H-pyrazole (749 mg, 11.0 mmol) and K2CO3 (4.1 g, 30.0 mmol) was stirred in DMF (15 mL) at 80° C. for 16 hours. The reaction mixture was poured into water and extracted with EtOAc (3×). The organics were combined, washed with water (3×), brine, dried (Na2SO4) and evaporated to dryness. Purification by column chromatography (5 to 30% EtOAc in hexanes) gave the desired product (0.7 g, 40%) as a white solid. ESI-MS m/z calc. 179.3. found 180.3 (M+1)+. Retention time: 0.74 minutes (3 min run).
