Procedure

tert-Butyl 5-(benzyloxy)-2-{(1-[4′-({[tert-butyl(dimethyl)silyl]oxy}methyl)biphenyl-4-yl]piperidin-4-yl}methyl)-6-methylpyrimidine-4-carboxylate (0.98 g, 1.4 mmol) was dissolved in 1,4-dioxane (10 mL), and a solution of hydrogen chloride in dioxane (4 M, 1.0 mL, 4 mmol) was added, followed by stirring at room temperature for 1.5 hours. A saturated sodium hydrogencarbonate solution was added to the reaction solution for neutralization, followed by extraction with ethyl acetate, and subsequently the organic layer was concentrated under reduced pressure to afford the title compound (0.81 g, 1.4 mmol) as a yellow oil (yield 99%).
