Procedure

Water (2 ml) and 4N aqueous solution of sodium hydroxide (2 ml) were added to a solution of 1-(3-chloro-5-cyclopropylpyridin-2-yl)-5-methyl-1H-pyrazole-4-carboxylic acid ethyl ester (240 mg) in ethanol (4 ml) at room temperature, and stirred at 90° C. for six hours. After completion of the reaction, the reaction solution was cooled to 0° C. and 1N hydrochloric acid aqueous solution (9 ml) was added. The precipitated solid was collected by filtration to give the titled compound (157 mg) as a light brown solid.
