Iodoethane → HCID 66831765, compound

Participants

Reaction Steps

Sodium hydride (0.141 g; 3.51 mmol) was added to a solution of ethyl 5-(hydroxymethyl)-4,5-dihydroisoxazole-3-carboxylate (0.338 g; 1.76 mmol) in DMF (3 mL) in an ice bath. The mixture was stirred for 10 min before addition of iodoethane (0.430 mL; 5.27 mmol). The ice bath was removed and the mixture was stirred at room temperature for 2 h. After evaporation, the residue was partitioned between brine and dichloromethane and the solution extracted with dichloromethane. Organic extracts were evaporated and the residue was purified by flash chromatography on silica gel (eluent: 1-6% ethyl acetate in dichloromethane) to afford 0.142 g (40%) of ethyl 5-(ethoxymethyl)-4,5-dihydroisoxazole-3-carboxylate.
