Methyl 4-hydroxybenzoate (10 g, 66 mmoles) was dissolved in N,N-dimethylformamide (200 mL). Potassium carbonate (45 g, 0.33 moles) and 4-(2-chloroethyl)morpholine hydrochloride (18.3 g, 99 mmoles) were added and the resulting mixture was stirred vigorously at room temperature for 5 days. The reaction mixture was poured into water (500 mL) and extraction with ethyl acetate (2×250 mL), washing of the combined organic phases with water (200 mL), drying over MgSO4 and evaporation afforded 16.8 g (96%) of methyl 4-(2-morpholin-4-ylethoxy)benzoate as an oil.
