A 4.53 g (20.9 mmoles) quantity of 3-chloromethyl-5-nitrosalicylaldehyde and 5.48 g (20.9 mmoles) of triphenylphosphine were dissolved in 30 ml of benzene and the solution obtained was refluxed with heating for 8 hours. After the reaction, the precipitate obtained was isolated by filtration, washed thoroughly with acetone and dried, giving 8.63 g (yield: 86%) of 3-formyl-2-hydroxy-5-nitrobenzyltriphenylphosphonium chloride as a yellow powder.
