Procedure

To a solution of methyl 2-((3R,5R,6S)-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-methyl-1-((S)-1-(N-(oxetan-3-yl)sulfamoyl)butan-2-yl)-2-oxopiperidin-3-yl)acetate (41.1 mg, 0.069 mmol; Example 372, Step C) in THF (2.0 ml) and MeOH (1.0 ml) was added 1 N lithium hydroxide (3.0 ml, 3.0 mmol). The suspension was stirred at room temperature for 15 hours, then acidified to pH 4 using 1 N HCl, and then concentrated in vacuo. Purification of the residue by chromatography on silica gel (4 g SiO2, 5 to 25% gradient of a 1:6.5 MeOH/acetone mixture in hexanes) provided the title compound. The material was purified further by reversed phase preparatory HPLC (Eclipse Plus C18, 30×250 mm, 5 um column; Agilent, Santa Clara, Calif.) (eluent: 0.1% TFA in acetonitrile/water, gradient 30% to 60% over 25 min) to provide the title compound, as a white solid.
