2-(甲基硫烷基)乙基]脲

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: There are slowly added 3 ml of H2O2 (110 volumes) to a well agitated solution of 20 moles of 2-methylthio ethylurea in a mixture of ethanol and formic acid. The solution obtained is agitated for 2 hours after which it is concentrated under reduced pressure. The resulting residue is then crystallized in ethylacetate thus providing white crystals melting at 88° C. in a yield of 85%. The solution obtained is concentrated under reduced pressure The resulting residue is then crystallized in ethylacetate
