Tetrahydrofuran → HCID 53903233, compound

Participants

Reaction Steps

A mixture of 14.5 g (0.110 mole) of malonic acid mono ethyl ester, 19.0 g (0.220 mole) of magnesium methoxide and anhydrous tetrahydrofuran is heated with stirring under nitrogen allowing the methanol produced to distill off. To this mixture is added 45.0 g (0.105 mole) of N-[5-(9,12,15-octadecatrien-1-yloxy)-2-thenoyl]imidazole with stirring and cooling on an ice bath for four hours. The solvent is removed and the residue diluted with ice-concentrated HCl (1:1) solution to give 5-(9,12,15-octadecatrien-1-yloxy)then-2-oylacetic acid ethyl ester.
