Reaction Steps
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 H and CH3Cl2. The biphasic mixture was filtered, the organic phase collected, washed with saturated NaHCO 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/CH3Cl2. Concentration of similar fractions afforded 0.7 g of the compound as a pale yellow solid, m.p. 99°-101° C.
