Procedure

A mixture of 18 g of methyl 4-(benzyloxy)-6-((1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazol-3-yl)amino)pyridine-2-carboxylate dissolved in 200 ml of methanol with 200 ml of tetrahydrofuran was charged with 1.8 g of 20% palladium hydroxide on carbon catalyst, and the mixture was stirred at room temperature for 2 hours under hydrogen atmosphere at 1 atm. The reaction mixture was filtered and concentrated to give crude title compound.
