Reaction Steps

Combine 5-[4-(2-nitro-phenyl)-oxazol-2-yl]-pentanoic acid methyl ester (2.5 g, 8.2 mmol) with 5% Pd/C (300 mg) and Pd/black (50 mg) in THF and react with hydrogen (init. 39 psi) in a Parr® apparatus. When reduction is complete, filter the mixture through, Celite® and concentrate the filtrate. Chromatograph the residue over silica gel (MeOH/CH2Cl2) to allow for recovery of 2.05 g (91%) of 5-[4-(2-amino-phenyl)-oxazol-2-yl]-pentanoic acid methyl ester. MS (ES): (M+1)+ 275.1, 276.2 m/z.
