Reaction Steps

4-[1-(4-tert-Butylphenylamino)ethyl]-N-(2H-tetrazol-5-yl)benzamide (100 mg, 0.28 mmol) and 4-trifluoromethoxyphenyl isocyanate (70 mg, 0.30 mmol) was dissolved in DMF (0.6 mL) and the solution was heated to 80° C. for 3 hours. The mixture was cooled to room temperature and subsequently taken to dryness using rotary evaporation. The residual oil was dissolved in a minimum of DMF/acetonitrile (1:1), and submitted to preparative HPLC purification. Pure fractions were pooled and concentrated to dryness to afford 10 mg (8%) of the title compound.
