Reaktionsschritte

In analogy to intermediate 40B, 3,4-bis(trifluoromethyl)aniline and ethyl 2-bromopropionate with 2,6-lutidine were heated for 20 h at 82° C., diluted with acetonitrile and treated with 1 equivalent of ethyl 2-bromopropionate and 2,6-lutidine and refluxed for 2 days, treated again with 1 equivalent of ethyl 2-bromopropionate and 2,6-lutidine and continued to reflux for 2 days. Workup and purification by flash silica gel column (n-heptane/ethyl acetate 9:1 to 2:1) yielded 49% of the titled compound as yellow oil. MS: 328.08 (M−H−).
