Reaction Steps
A mixture of 1.1 g (4.0 mmol) methyl 2-(4-fluorophenyl)benzo[d]oxazole-4-carboxylate 9d and 3.7 mL of 3N aqueous NaOH in 10 mL of THF was refluxed overnight. After cooling the reaction mixture was poured into water and acidified with conc. HCl. The resulting solid was filtered and dried to give 830 mg (79%) of 2-(4-fluorophenyl)-benzo[d]oxazole-4-carboxylic acid, 9e. MS m/z (M+H+) 258.1.
