Procedure
N-(2-(cis-4-Amino-cyclohexylamino)-2-oxoethyl)-3-(trifluoromethyl)benzamide hydrochloride (50 mg, 0.132 mmol, 1 eq), 4-hydroxy-4-(pyridin-2-yl)cyclohexanone (25 mg, 0.132 mmol, 1 eq) and sodium triacetoxyborohydride (56 mg, 0.263 mmol, 2 eq) were stirred in 2% acetic acid/methylene chloride (10 mL) at room temperature for 20 hours. Worked up by adding saturated sodium bicarbonate (10 mL). Stirred 10 minutes then extracted 3 times with methylene chloride (10 mL). The organic layers were combined, dried (sodium sulfate) and stripped to give an oil. Purified over silica gel in 100% ethyl acetate to 4:1 methylene chloride/methanol to give N-(2-(cis-4-(cis- and trans-4-hydroxy-4-(pyridin-2-yl)cyclohexylamino)cyclohexylamino)-2-oxoethyl)-3-(trifluoromethyl)benzamide (35 mg) as a white solid. MS found: (M+H)+=519.27.
