실험 절차

To a solution of n-propanol (224 mg, 3.74 mmol) in THF (10 mL) was added NaH (112 mg, 2.80 mmol, 60% in mineral oil) at 0° C. After stirring at 0° C. for 30 min, 2-bromo-4-(ethanesulfonyl)-1-fluorobenzene (500 mg, 1.87 mmol) was added and the mixture was stirred at room temperature for 4 h. Addition of saturated NH4Cl (10 mL) followed by EA extractive work up gave the title compound (300 mg, yield: 52.3%) which was carried on directly.
