Reaction Steps

To a solution of methyl 4-hydroxybenzoate (1.0 g, 6.58 mmol), 3-dimethylamino-1-propanol (1.01 g, 9.87 mmol), and triphenylphosphine (2.6 g, 9.87 mmol) at 0° C. in THF (20 mL) was added dropwise diisopropyl azodicarboxylate (1.99 g, 9.87 mmol). After stirring for 16 h at room temperature the solution was concentrated and the residue purified by column chromatography (silica gel, methanol/dichloromethane) to yield the title compound as an oily solid (1.25 g, 5.2 mmol). MS(ESI): 238.1 (M+H)+.
