Participants

Reaction Steps

To 4-bromo-2,5-difluoro-phenol (595, 0.90 g, 0.0043 mol, prepared as described in Example 34, Scheme 61) in N,N-dimethylformamide (30.0 mL) were added sodium hydride (0.21 g, 60% in mineral oil, 0.0052 mol) and benzyl bromide (0.563 mL, 0.00474 mol). The reaction was stirred at room temperature overnight. The reaction was poured into water and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with 5% ethyl acetate in hexane to give a white solid (600, 0.84 g, 65.0%).
