To a solution of 4-(4-chlorophenyl)cyclohexanecarboxylic acid (1.01 g, 4.231 mmol) and triethylamine (0.5897 ml, 4.231 mmol) in tert-butanol (22 ml) was added diphenyl phosphorazidate (0.9147 ml, 4.231 mmol), and the reaction was heated to reflux for 16 hours. The reaction was diluted with EtOAc and washed with 1M hydrochloric acid, saturated sodium bicarbonate, and saturated sodium chloride. The organic layer was dried over anhydrous sodium sulfate, filtered, and concentrated. The crude material was on a Biotage SP1 system eluting with a linear gradient of 5-50% EtOAc in hexanes to yield 760 mg of the title compound (57% yield).
