Reaction Steps

2-Chloro-N-((R)-1-((S)-4-(4-chlorophenyl)-4-hydroxy-3,3-dimethylpiperidin-1-yl)-3-methyl-1-oxobutan-2-yl)acetamide (35 mg, 0.084 mmol), potassium carbonate (35 mg, 0.253 mmol), methyl 2-hydroxybenzoate (13 mg, 0.084 mmol) and DMSO (3 mL) were mixed with stirring at 25° C. The reaction was stirred for 20 hours, diluted with EtOAc, and then rinsed 4 times with water. The organic layer was dried over sodium sulfate and concentrated in vacuo to give an amber oil which was purified over silica gel in (3:1 to 1:1 hexanes/EtOAc to 100% EtOAc) to obtain methyl 2-(2-((R)-1-((S)-4-(4-chlorophenyl)-4-hydroxy-3,3-dimethylpiperidin-1-yl)-3-methyl-1-oxobutan-2-ylamino)-2-oxoethoxy)benzoate (18 mg, 0.034 mmol, 40% yield) as a white glass. MS found: (M+H)+=531.21.
