A solution of methyl 4-(5-methyl-4-((4-(trifluoromethyl)phenylsulfonyl)methyl)oxazol-2-yl)benzoate (700 mg, 1.59 mmol, 1.00 equiv) in 6N hydrochloric acid (30 mL) was refluxed for 8 h. The reaction mixture was cooled to room temperature and diluted with 100 g of water/ice. The solid was collected by filtration, washed with 2×20 mL of water and dried in a vacuum oven to afford 0.6 g (89%) of 4-(5-methyl-4-((4-(trifluoromethyl)phenylsulfonyl)methyl)oxazol-2-yl)benzoic acid as a white solid.
