Procedure
Sodium dihydro bis (2-methoxyethoxy) aluminate (7.25 g. 0.025 m) was added dropwise to a solution of 2-(4-ethoxycarbonylstyryl) pyridine (6.35 g 0.25 m) in 100 ml dry ether. The mixture was stirred for 3 hours at room temperature followed by gently refluxing for a further 3 hours. On cooling, 20% sodium hydroxide solution was added to the reaction mixture. The ether layer was separated and dried over anhydrous magnesium sulphate. The solvent was removed by rotary evaporation and the solid which was removed was recrystallised from ethanol. The product was identified and shown to be pure by G.L.C. I.R. N.M.R. and analysis.
