反应条件

实验过程

The title compound was prepared in three steps as described in Procedure D. In the first step, ethylenediamine was reacted in acetonitrile with 3-(trifluoromethoxy)benzoylchloride (2 eq) in the presence of TEA to give the N,N′-dibenzoylated ethylenediamine upon aqueous work-up. After the last step (reaction with cyanogen bromide), the crude product was isolated upon aqueous work-up, recrystallized from diethyl ether and the title compound isolated as the hydrogen bromide salt. MS (ES+) m/z 434 ([M+1]+, 100); HR-MS: 434.1299 ([M+1]+, C19H18F6N3O2; calc. 434.13032).
