This material, tert-butyl (1-benzylpiperidin-4-yl)methyl(7-(bis((2-(trimethylsilyl)ethoxy)methyl)amino)-3-(6-fluoroquinolin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)carbamate, was then stirred with Pd(OH)2/C (0.2 equiv) and ammonium formate (20 equiv) in ethanol at 80° C. until the reaction was deemed complete by HPLC, LC-MS, or TLC analysis. The mixture was allowed to cool to room temperature, filtered through a pad of celite, concentrated and purified on silica gel to afford compound tea-butyl 7-(bis((2-(trimethylsilyl)ethoxy)methyl)amino)-3-(6-fluoroquinolin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl(piperidin-4-ylmethyl)carbamate.
