실험 절차

To a solution of tert-butyl 4-((S)-2-((3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-methyl-2-oxopiperidin-1-yl)butyl)piperazine-1-carboxylate (Example 95, Step A) (187 mg, 0.304 mmol in DCM (2.4 mL) was added TFA (600 μL, 7.79 mmol). The reaction mixture was stirred at room temperature for 16 hours before concentrating under reduced pressure. The residue was taken up in DCM (15 mL) and washed with sat. sodium bicarbonate solution (10 mL) and saturated sodium chloride solution (10 mL). The organic layer was dried over sodium sulfate, filtered and the filtrate concentrated under reduced pressure to afford the title compound as a white foam.
