Potassium Carbonate → 3-[4-(3-Hydroxybutoxy)phenyl]-5-methoxymethyl-2-oxazolidinone

Participants

Reaction Steps

To a solution of 27.5 g (0.112 mol) of 1-tosyloxy-3-butanol in 250 ml of methylethylketone, are added 28.2 g (0.2 mol) of K2CO3 and 22.8 g (0.102 mol) of 3-(4-hydroxyphenyl)-5-methoxymethyl-2-oxazolidinone (code number MD 780232). The mixture is heated under reflux for 4 h 30. After filtration and concentration, the residue is taken up in 200 ml of CH2Cl2, the organic phase is washed with NaCl saturated water, dried over Na2SO4 and concentrated. After purification by flash chromatography silica, eluent: CH2Cl2 : 98; CH3OH: 2), the aimed product is obtained with a 70% yield, m.p.: 58° C.;
