Methyl 2-(1-tert-butoxycarbonylpiperidin-4-yloxy)-4-hydroxybenzoate (9.13 g, 26.0 mmol) was dissolved in DMF. Potassium carbonate (7.19 g, 52.0 mmol) was added, followed by methoxymethyl chloride (2.51 g, 31.2 mmol), and the reaction was stirred at room temperature under a drying tube for 24 h. An additional 1.2 eq of methoxymethyl chloride was added and the reaction stirred an additional 48 h. The DMF was removed in vacuo. The residue was dissolved in ethyl acetate, washed with water, dried, and the solvent was removed in vacuo to give 9.91 g (96.2%) of a viscous oil.
