実験手順

(S)-4-(4-chlorophenyl)-3,3-dimethylpiperidin-4-ol (100 mg, 0.417 mmol), (R)-2-(tert-butoxycarbonyl(methyl)amino)-3-methylbutanoic acid (116 mg, 0.501 mmol), HOBT (77 mg, 0.501 mmol), EDC (96 mg, 0.501 mmol) and triethylamine (0.116 mL, 0.834 mmol) were mixed in methylene chloride (3 mL) at 25° C. with stirring. The reaction was stirred for 20 hours then washed with sat'd sodium bicarbonate. The methylene chloride layer was dried over sodium sulfate and concentrated in vacuo to give a white glass which was purified over silica gel (9:1 to 3:1 to 1:1 Hexanes/EtOAc) to obtain tert-butyl (R)-1-((S)-4-(4-chlorophenyl)-4-hydroxy-3,3-dimethylpiperidin-1-yl)-3-methyl-1-oxobutan-2-yl(methyl)carbamate (190 mg, 0.417 mmol, 100% yield) as a white glass. MS found: (M+H)+=453.15.
