preparation of amitraz
« on: August 16, 2005, 04:14:22 AM »
hi all,
iam a university student on attachment and iam working on a project to make amitraz, a pesticide active ingridient. i have identified three raw materials which are triethyl orthoformate, methylamine and 2,4-xylidine. however, it has been difficult to come up with the right conditions as they are highly reactive materials and iam producing alot of by-products. also, i was thinking whether the following compound exists or if can be made: (CHO)2N(CH3)
thank you all

These are hits copied straight from beilstein, cos I can't be bothered to format them or owt - your dodgy looking compound can certainly be made though!  Enjoy....
