Procedure

To a solution of 43 mg (0.09 mmol) of 3-((3R,5R,6S)-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-methyl-2-oxo-1-(pentan-3-yl)piperidin-3-yl)-2-hydroxypropanoic acid (Example 81, Step B) in DMF (5 mL) was added 67 mg (0.18 mmol) of HATU, 58.5 mg (0.35 mmol) of 2,4-dimethoxybenzylamine and 36 μL (0.26 mmol) of triethylamine. The resulting yellow solution was stirred at room temperature for 1.1 h, and then was partitioned between saturated aqueous sodium bicarbonate and EtOAc (2×). The combined organic layers were dried over Na2SO4, filtered and the filtrate was concentrated. The crude title compound (mixture of alcohol epimers) was used directly in the next step.
