Reaction Steps

To a solution of [4-(2-azepan-1-ylethoxy)benzyl] (2-benzyloxyethyl) {5-(tert-butyldimethylsilyloxy)-2-[6-(tert-butyldimethylsilyloxy)-1,2,3,4-tetrahydronaphthalen-2-yl]phenyl}amine (450 mg) in dichloromethane (23 ml) was added dropwise boron trichloride (1.0 M solution in dichloromethane) (4.2 ml) at −78° C., and the solution was stirred for 30 minutes. At −78° C., to the reaction solution was added methanol (2 ml), and the reaction mixture was diluted with a saturated aqueous solution of sodium bicarbonate. The solution was extracted with chloroform, then washed with brine, dried over anhydrous magnesium sulfate, and then the solvent was evaporated in vacuo. The residue was purified by NH silica gel column chromatography (hexane-ethyl acetate system) to provide the title compound (240 mg).
