반응 단계
A solution of 1-[4-(3-chloropropoxy)-3-methoxyphenyl]ethanone (4.3 g, 17.7 mmol), [bis(trifluoroacetoxy)iodo]benzene (15.6 g, 36.2 mmol), H2O (18 ml), CF3CO2H (2.8 ml) and CH3CN (90 ml) was refluxed for 3 hours. The CH3CN was removed under reduced pressure and the resulting yellow liquid was partitioned between H2O and CH2Cl2. The biphasic mixture was filtered, the organic phase collected, washed with saturated NaHCO3 solution and concentrated to afford 1.5 g of an amorphous brown solid. The solid was flash chromatographed on silica gel, eluting the column with 5% EtOAc/CH2Cl2. Concentration of similar fractions afforded 0.7 g of the compound as a pale yellow solid, m.p. 99°-101 ° C.
