Procedure

To a solution of 75.0 g (carbethoxyethylidene)triphenyl phosphorane in 350 ml of toluene, 23.2 g of salicylaldehyde was dropped in at 20° C. while cooling in an ice-bath. After stirring at room temperature for 90 mn., the reaction mixture was diluted with toluene and washed to neutrality with water.
