Participants

Reaction Steps

A solution of n-butyllithium in hexane (1.5 M, 5.7 ml) was added dropwise a solution of tert-butyl (1-benzyl-4-piperidinyl)((1-((2-(trimethylsilyl)ethoxy)methyl)-1H-imidazol-4-yl)methyl)carbamate (3.9 g) obtained in Example 83c) in THF (50 ml) at −40° C. under argon atmosphere. The reaction solution was mixed at −40° C. for 15 minutes, and then DMF (72 ml) was mixed, and mixed at room temperature for 15 hours. To the reaction solution was added a saturated aqueous ammonium chloride solution and extracted with ethyl acetate. The extract was washed with saturated brine and dried over anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure. The residue was purified with silica gel column (ethyl acetate:ethanol=10:1) to obtain the title compound as a pale yellow oil (2.5 g, 61%).
