Conditions

Workup

1. 1
   Otherthe crude product was isolated upon aqueous work-up

Procedure

The title compound was prepared from N-phenylethylenediamine in four steps by Procedure A. In the first step, one equivalent of Boc2O was used and, similarly, one equivalent of 3,4-difluorobenzyl bromide was used as benzylating reagent in the second step. After reacting with cyanogen bromide, the crude product was isolated upon aqueous work-up and purified by preparative LCMS to give the title compound as the free base. MS (ES+) m/z 288 ([M+1]+, 100); HR-MS: 288.1316 ([M+1]+, C16H16F2N3; calc. 288.131228).
