반응 단계

A solution of 2-(2-hydroxyethyl)-5-methoxy-1-indanone (105 mg, 0.51 mmol) in methanol (2.0 mL) at room temperature was treated with ethyl vinyl ketone (EVK, 0.102 mL) and 0.5M sodium methoxide in methanol (0.204 mL, 0.1 mmol). The mixture was stirred in a capped flask and heated in an oil bath at 60° C. for 8 hours. After cooling, the reaction mixture was diluted with EtOAc (25 mL), washed with 0.2N HCl (15 mL), water (15 mL), and brine (15 mL), dried over MgSO4, filtered, and evaporated under vacuum to afford 2-(2-hydroxyethyl)-5-methoxy-2-(3-oxopentyl)-1-indanone (138 mg, 93% yield) as an oil.
