실험 절차

To a solution of 4-(4-methoxy-phenoxy)-3,5-dimethyl-nitrobenzene (2.7 g, 10 mmol) and p-fluorobenzoyl chloride (4.0 g, 3.0 mL, 25 mmol) in methylene chloride (10 mL) was added titanium tetrachloride (1M in methylene chloride, 50 mL, 50 mmol). The reaction mixture was stirred at room temperature for 3 d, poured into ice (100 g), and stirred 1 h. The organic layer was separated and the aqueous layer was extracted with methylene chloride (3×50 mL). The combined organic extracts were washed with 5% sodium carbonate (200 mL), brine (150 mL), dried and concentrated. The residue was triturated with ether-petroleum ether. The solid was collected by filtration to give the title compound of Step A (2.1 g) as a tan solid. MS (APCl−) Calc.: 395.2. Found: 394.2 (M−1).
