Reaction Steps

A mixture of 4M HCl solution in Dioxane (1 mL) and (R)-methyl 4-((tert-butoxycarbonyl)amino)-1-(5-(2-(2,5-difluorophenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyridine-3-carbonyl)piperidine-4-carboxylate (50 g, 0.085 mmol) was stirred at 20-35° C. for 3 h. After which the reaction mixture was concentrated under reduced pressure to afford the crude. The residue obtained was dissolved in water, extracted with ethylacetate, washed with saturated NaHCO3 solution followed by brine and dried over anhydrous sodium sulfate, concentrated under reduced pressure to afford 15 mg of the title compound.
