Procedure

Dissolve (2-phenyl-benzoxazol-5-yl-methyl)-carbamic acid 2-trimethylsilanyl-ethyl ester (0.4, 0.99 mmol) in anhydrous THF (5 mL) and treat with 1M tetrabutylammonium fluoride in THF (1.5 mL, 1.54 mmol). Heat the mixture at reflux for 30 min, evaporate the solvent and purify by SCX chromatography to obtain the title compound as a yellow oil (0.1 g, 27%).
