The reaction mixture was stirred at 0 C. for 5 min. To the reaction mixture was added 2-methyl-3-phenyl-4,5,6,7-tetrahydropyrazolo[3,4-c]pyridine, Intermediate 1 (55 mg, 0.258 mmol) at 0 C. The reaction mixture was allowed to warm to room temperature and stirred for 18 h. The reaction mixture was diluted with water (2 mL) and extracted with ethyl acetate (2*5 mL). The combined organic layers were washed with 10% potassium bisulfate (1*5 mL), 1 M sodium carbonate (1*5 mL) and brine (1*5 mL), dried over magnesium sulfate, filtered and evaporated. The residue was purified by reverse phase HPLC to afford the title compound (14 mg, 0.036 mmol, 13%) as an off-white powder.
