Reaction Steps
To a solution of 4-hydroxymethylbenzoic acid (1 g) in DCM (66 mL) was added imidazole (985 mg, 2.2 equiv) followed by the addition of t-butyldimethylsilyl chloride (TBSCl) (1.09 g, 1.1 equiv). The reaction mixture was stirred at room temperature for 3 days and was diluted with DCM (50 mL) and 1 N HCl. The aqueous phase was extracted with DCM, and the combined organic extracts were dried over sodium sulfate and concentrated in vacuo to provide the title compound (1.44 g, 82% yield).
