Another method for producing DCC from dicyclohexylurea is a two-step process using phosphoryl chloride in dichloromethane at 40 C° for 4 h under non-basic conditions followed by removal of acidic components with aq. sodium hydroxide. This method, which gives an 89% yield of DCC, has been presented in a patent application.

Reaction Conditions:
with bis(trichloromethyl) carbonate in 1-methyl-pyrrolidin-2-one at 30 - 40; for 6 h;Autoclave;
Steps:
3 Example 1
1000 ml of NMP and 100 g of DCU were added to the autoclave at 30 ° C, stirred well, 200 g of BTC was added, and thenAdding the composite catalyst (the dosage ratio of DCU and composite catalyst is 1: 0.0001), raising the temperature to 40 DEG C,Reaction 6h, after the completion of the reaction, add triethylamine to adjust the pH to 7.5, hot filter, atmospheric distillation of the solvent, and then vacuum distillationDistillate, collecting 155 ± 1 ° C distillate, in the oven vacuum drying to obtain a white crystalline solid DCC.
