Participants

Reaction Steps

N-(3-trifluoromethylphenacyl) phthalamic acid (9.4 g, 0.027 mol) was added portionwise to conc. sulfuric acid (30 ml) at <10° C. The resultant solution was stirred for 20 hours at room temperature and poured into 600 ml of ice-water to yield 8.2 g of crude 2-[5-(3-trifluoromethylphenyl)-1,3-oxazol-2-yl]benzoic acid as a brown solid; ir (CHCl3) 1720 cm-1. The crude acid was used for subsequent synthesis as obtained.
