Reaction Conditions:
in dichloromethane at 26; for 0.5 h;Inert atmosphere;Temperature;
Steps:
1.2; 1.3; 2.2; 2.3; 3.2; 3.3; 4.2; 4.3
Add 0.04 mol of triphosgene and 200 ml of dichloromethane to a three-necked flask.Stir until the phosgene dissolves,Cool the mixture to 26 ° C,Under nitrogen protection conditions,To the mixture, N-trimethylsilazole 0.28 mol was added dropwise.The dropping time is 30 min, that is, the product carbonyl diimidazole reaction liquid is obtained;(3) The carbonyl diimidazole reaction liquid prepared in the step (2) is filtered, and the filtered product is subjected to vacuum drying at a temperature of 72 ° C to obtain a powdery carbonyl diimidazole.
