Reaction Steps

To a stirred solution of 6-((tert-butoxycarbonyl)methyl)-7-(2,4-dichlorophenyl)-5-methyl-[1,2,4]triazolo[1,5-a]pyrimidine-2-carboxylate (13 mg, 0.03 mmol) in THF (1 mL) was added LiOH-H2O (9 mg, 0.21 mmol) in H2O (0.1 mL). After heating to 40° C. for 1 h, the reaction was concentrated under reduced pressure and diluted with EtOAc. The organic layer was washed with 1N HCl and brine prior to drying over anhydrous MgSO4. Filtration, concentration under reduced pressure afforded 6-((tert-butoxycarbonyl)methyl)-7-(2,4-dichlorophenyl)-5-methyl-[1,2,4]triazolo[1,5-a]pyrimidine-2-carboxylic acid (13 mg, 100%) as a white solid.
