실험 절차

A mixture of N-((S)-6-bromo-1,2,3,4-tetrahydronaphthalen-2-yl)-4-[(S)-1-(tetrahydrofuran-2-yl)methoxy]benzamide (1.0 g) and THF (10 ml) was cooled to −78° C. (dry ice bath), and a solution of methyllithium (2.0 ml; 1.6 M in diethyl ether) was added dropwise. One minute after the addition had ended, a solution of butyllithium (1.4 ml; 2.5 M in toluene) was added dropwise. One minute after the addition had ended, acetone (0.14 g) was added. After warming to room temperature, the reaction mixture was diluted with water and extracted with ethyl acetate. The organic phases were dried over magnesium sulfate and concentrated. The residue was chromatographed on silica gel (eluent: 1:2 heptane/ethyl acetate). The product was thus obtained with the molecular weight of 409.53 (C25H31NO4); MS (ESI): 410 (M+H+).
