Procedure
A mixture of benzyl 2-(oxazol-2-yl)propan-2-ylcarbamate (0.63 g, 24 mmol) and palladium 10% on carbon (0.06 g) in ethanol (20 mL) was charged with hydrogen balloon and stirred at room temperature for 2 h. TLC showed the reaction was completed; it was filtered and concentrated to give a yellow oil (0.1 g, 33%); MS: m/e 127.1 [M+H]+. 1H NMR (300 MHz, CDCl3): δ 7.58 (d, 1H, J=0.6 Hz), 7.02 (s, 1H), 2.56 (bs, 4H), 1.59 (s, 6H).
