The solvent was removed and the residue was triturated with ethyl acetate, followed by filtration, to afford 4-(4-{4-[(2-phenyl-5-trifluoromethyl-oxazole-4-carbonyl)-amino]-phenyl}-[1,4]diazepan-1-ylmethyl)-benzoic acid as a yellow solid (20 mg, 29% yield) LCMS for C30H27F3N4O4 calcd. (m/e) 564, observed 565 (M+H).
