Reaction Steps

To a cold (0° C.) solution of morpholine-3-carboxylic acid (5-tert-butyl-isoxazol-3-yl)-amide; hydrochloride (50 mg; 0.115 mmol), 4,4-difluorocyclohexanecarboxylic acid (18.9 mg, 0.115 mmol) and N,N-diisopropylethylamine (0.052 mL; 0.3 mmol) in anhydrous acetonitrile (2 mL) is added phosphorous oxychloride (0.01 mL; 0.115 mmol). The reaction mixture is left stirring at room temperature for 18 hours. After this time, the reaction mixture is quenched with saturated NH4Cl aqueous solution and extracted with ethyl acetate twice. The organics are combined and washed with brine, dried over Na2SO4, filtered and concentrated under reduced pressure. Purification by preparative LC-MS provides the title compound, m/z 400 [M+H+].
