Reaction Steps

Combined methyl 6-(4-(4-cyanophenyl)-5-((2-(trimethylsilyl)ethoxy)methoxy)-1H-pyrazol-1-yl)-4-methylnicotinate (8.67 g, 25.96 mmol), methanol (50 mL), water (50 mL) and LiOH (3.27 g, 77.87 mmol). The reaction mixture was stirred at room temperature for 6 h and at 50° C. overnight. The reaction mixture was concentrated to remove most of the methanol and then the pH was adjusted to 3 by addition of 3N HCl to give a solid. The solid was collected by filtration and dried in vacuum to give the title compound (4.3 g, 51.76%).
