Yield:10591-85-2 98.5%

Reaction Conditions:

with dihydrogen peroxide;sodium hydroxide at 35 - 40; for 3 h;

Steps:

Example
The 4.4g of sodium hydroxide, 3g of a phase transfer catalyst, 19.7g of benzylamine were put into two four-necked flask, 400ml of distilled water was added, open a stirrer, and stirred to dissolve it; then, when the temperature rose to 35 , , 9.2g slowly added dropwise carbon disulfide (time control 2.5h), condensation reaction, addition was complete, then incubation was continued for 0.5 hours; when the temperature rose to 40 , then hydrogen peroxide was added dropwise 6g (control time 3 hours) ; after completion of the oxidation reaction, sulfuric acid was added dropwise to adjust the pH (6 ~ 7), then stirring was continued incubation IH; Finally, the material, suction filtration, washed with ethanol 3 times; the product was dried at 80 deg.] C for 4 hours. To obtain the product 26.8g, a yield of 98.5%, content (HPLC) is greater than 97%, melting point 128.2 , as a pale yellow powder
