Reaction Steps

To a stirred solution of 5-(4-methoxyphenyl)-2-(phenylamino)oxazole-4-carboxylic acid (0.012 g, 0.039 mmol), 1-hydroxybenzotriazole hydrate (0.009 g, 0.059 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.011 g, 0.057 mmol) in DMF (5 mL) was added a 0.5M ammonia in dioxane solution (0.116 mL, 0.058 mmol) and the resulting mixture stirred at room temperature overnight. The solvent was removed in vacuo and the residue purified by preparative HPLC to afford 5-(4-methoxyphenyl)-2-(phenylamino)oxazole-4-carboxamide (0.0045 g, 0.015 mmol, 38%). 1H NMR (DMSO) δ 3.82 (3H, s), 6.98 (1H, t), 7.04 (2H, d), 7.33 (2H, t), 7.51 (1H, br, s), 7.60 (1H, br, s), 7.73 (2H, d), 8.16 (2H, d), 10.40 (1H, s). LCMS (2) Rt: 2.67 min; m/z (ES+) 310.
