Reaction Steps

To a solution of 3-{[3-(4,5-diphenyloxazol-2-yl)-bicyclo[2.2.1]hept-2-en-2-yl]methyl}benzoic acid (0.46 g) in a THF (10 ml) were added isobutyl chloroformate (0.26 ml) and triethylamine (0.3 ml) at 0° C. under N2. After being stirred for 30 minutes, NH3 (5 ml, 4M solution in methanol) was added to the mixture. After being stirred for 30 minutes, the solvent was removed in vacuo. The residue was partitioned between ethyl acetate and lN-NaOH and the organic layer was washed with brine. The dried solvent was evaporated in vacuo to give 3-{[3-(4,5-diphenyloxazol-2-yl)bicyclo[2.2.1]hept-2-en-2-yl]methyl}benzamide (0.2 g).
