Procedure

N—((R)-1-((S)-4-(4-Chlorophenyl)-4-hydroxy-3,3-dimethylpiperidin-1-yl)-3-methyl-1-oxobutan-2-yl)cyclopentanecarboxamide (30 mg, 0.069 mmol) was dissolved into methylene chloride (2 mL) then cooled to −78° C. and DAST (13.3 mg, 0.083 mmol) was added. The reaction was stirred overnight at rt. HPLC showed some starting material present and 2 additional drops of DAST was added at rt. Some starting material was still present and 2 additional drops DAST was added and HPLC then showed the reaction was complete. The reaction was concentrated and Example 616 was isolated as a white solid by preparative reverse-phase HPLC (15.3 mg, 51% yield), M+H=437.38.
