実験手順

Under ice-cooling, to a solution of 3.0 g of tert-butyl 3-(3-fluorophenyl)-5-(hydroxymethyl)-1H-1-indazolecarboxylate in 30 ml methylene chloride were added 1.6 ml of triethylamine and 0.78 ml of methanesulfonyl chloride, and the mixture was stirred at room temperature for one day. To the reaction mixture was added 180 ml of ethyl acetate, and the mixture was sequentially washed with water, 1 N hydrochloric acid, water, saturated aqueous sodium hydrogencarbonate solution and brine, dried over anhydrous magnesium sulfate and the solvent was evaporated. The crude product was purified and separated by silica gel column chromatography (toluene), to give 2.74 g of the title compound as yellow crystals.
