Procedure

To a mixture of 52 mg of methyl 6-((1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazol-3-yl)amino)pyrazine-2-carboxylate, 0.5 ml of tetrahydrofuran and 1 ml of methanol was added an aqueous sodium hydroxide solution (1.0 M, 0.5 ml), followed by stirring at room temperature for 15 hours. The obtained reaction solution was diluted with ethyl acetate, and then washed with aqueous ammonium chloride and brine. The organic layer was dried over anhydrous magnesium sulfate and filtered, and filtrate was concentrated to give the title compound.
