Procedure

Acetyl chloride (7.8 μL, 0.11 mmol) was slowly added to a mixture of 1-cyclopentyl-3-ethyl-6-(1-piperidin-4-yl-1H-pyrazol-5-yl)-1H-indazole (20 mg, 0.055 mmol), triethylamine (15 μL, 0.11 mmol) in methylene chloride (2 mL), and the reaction was stirred for 16 hours at room temperature. Methylene chloride was added and the organic layer was washed with saturated sodium bicarbonate, water, then brine, dried, filtered and concentrated. The residue was dissolved in ethyl acetate and purified by silica gel column chromatography using 100% ethyl acetate as the eluent to afford 18 mg (81%) of 6-[1-(1-acetylpiperidin-4-yl)-1H-pyrazol-5-yl]-1-cyclopentyl-3-ethyl-1H-indazole. LC/MS (EI) tR 4.29 (Method C), m/z 406.3 (M++1).
