Reaction Steps

6-Methoxymethoxy-5,7,8-trimethyl-2,3-dihydro-4H-thiochromen-4-one (23 mg) was dissolved in anhydrous DMF (5 mL) and treated with 1,2-dichloroethane (6.8 μL) and NaH (60% in mineral oil, 8.2 mg), and stirred for 19 h at ambient temperature. The reaction mixture was poured into H2O and extracted with EtOAc. The organic layer was collected and dried over Na2SO4 followed by solvent evaporation. Column chromatography (SiO2: hexane:EtOAc, from 9:1 to 1:1 v/v) yielded a fraction containing impure desired product 6-methoxymethoxy-5,7,8-trimethyl-2,3-dihydro-4H-thiochromen-4-one (<1 mg).
