Reaction Steps

To a solution of methyl 2-(4-(bis(4-methoxybenzyl)amino)-2,6-difluorophenyl)-2-methylpropanoate (2.17 g, 4.62 mmol) in THF (30 mL) was added 1M DIBAL-H/THF solution (13.87 mL, 13.87 mmol) at 0° C., and the mixture was stirred at 0° C. for 5 hr. 1M DIBAL-H/THF solution (1.0 mL, 1.0 mmol) was added again thereto at 0° C., and the mixture was stirred at 0° C. for 1.5 hr. To the reaction mixture were added 1N hydrochloric acid and water, and the mixture was extracted with ethyl acetate. The organic layer was washed with brine, and dried over magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (solvent gradient; 3→50% ethyl acetate/hexane), and then silica gel column chromatography (NH, solvent gradient; 3→50% ethyl acetate/hexane) to give 2-(4-(bis(4-methoxybenzyl)amino)-2,6-difluorophenyl)-2-methylpropan-1-ol (1.310 g, 2.97 mmol, 64.2%) as a colorless oil.
