Procedure
To a solution of compound (viii) (9 mg, 0.02 mmol) in DCM (4 mL) at 0° C. were added DIPEA (30 μL, 0.17 mmol) and methanesulfonyl chloride (6 μL, 0.078 mmol). The reaction was stirred at 0° C. for 1 h, at which time it was diluted with DCM (12 mL) and saturated aqueous sodium bicarbonate (4 mL). The aqueous layer was separated and extracted with DCM (12 mL). The combined organic layers were washed with water (5 mL), dried (MgSO4) and evaporated to dryness. The residue was purified by flash column chromatography eluting with EtOAc/heptane (50-100%) to afford racemic 3-[5-cyclopropyl-3-(methylcarbamoyl)-2-(4-methylphenyl)-2H-indazol-6-yl]-3-(methylsulfonyl)propyl methanesulfonate (ix) as a white solid (8 mg, 69%).
