How is 5-(Chloromethyl)-1,2,3-tris(dodecyloxy)benzene (CAS: 162709-84-4) typically synthesized?

5-(Chloromethyl)-1,2,3-tris(dodecyloxy)benzene is typically synthesized through the reaction of 1,2,3-tris(dodecyloxy)benzene with phosgene in the presence of a catalyst such as dicyclohexylamine. The reaction is exothermic and should be carried out in a well-ventilated fume hood. The product is isolated by distillation or recrystallization, and the overall yield is around 70-80%.
