Reaction Steps

To a solution of 23 mg (0.071 mmol) of 4-((1R,2S)-2-{2-[4-(1H-tetrazol-1-yl)phenoxy]ethyl}cyclopropyl)piperidine in 0.6 ml anhydrous N,N-dimethylformamide at ambient temperature was added 0.020 ml (0.14 mmol) cyclohexylacetic acid, followed by 27 mg (0.14 mmol) EDC, 9.6 mg (0.071 mmol) HOBt, and 0.062 ml (0.35 mmol) diisopropylethylamine. The solution was stirred overnight at ambient temperature. The crude in N,N-dimethylformamide was purified directly by reverse phase HPLC (TMC Pro-Pac C18; 30-100% acetonitrile/0.1% formic acid in water gradient). The pure fractions were lyophilized to yield the title compound as white solid.
