Reaction Steps

2,4-Dichloropyrimidine (33.2 mg, 0.223 mmol) is added to the solution of (2S,4R)-4-Hydroxy-pyrrolidine-2-carboxylic acid (5-tert-butyl-isoxazol-3-yl)-amide; hydrochloride (66 mg, 0.223 mmol) and diisopropylethylamine (0.078 mL, 0.446 mmol) in ethanol (2 mL). The reaction is stirred at room temperature overnight. The reaction is quenched with saturated sodium bicarbonate 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 chromatography on silica eluting with methanol/dichloromethane provides the title compound. ESI m/z 366 [M+H+].
