実験手順

Tert-butyl 2-(4-hydroxyphenyl)acetate (200 mg, 0.960 mmol) was diluted with DMSO (4 mL) followed by the addition of K2CO3 (133 mg, 0.960 mmol) and N-(4-chlorophenethyl)-4-fluorobenzamide (267 mg, 0.960 mmol). The reaction was stirred at 85° C. overnight, and then stirred at 138° C. for 12 hours. The reaction was cooled to ambient temperature, diluted with DCM and 10% aq. sodium carbonate. The layers were separated and the organic layer was dried over MgSO4, filtered and concentrated. The crude material was purified by silica gel chromatography, eluting with hexanes:ethyl acetate (4:1) to yield tert-butyl 2-(4-(4-((4-chlorophenethyl)carbamoyl)phenoxy)phenyl)acetate (20 mg, 4.47% yield) as an off white solid.
