2,4-Difluorobenzoyl chloride → [2-Fluoro-4-(3-methyl-pyrazol-1-yl)-phenyl]-(11H-5-oxa-4,10-diaza-dibenzo[a,d]cyclohepten-10-yl)-methanone

Participants

Reaction Steps

The title compound may be prepared in a manner analogous to that of the 2-chloro analog of Example 16, by reacting 6H-pyrido[2,3-b][1,5]benzoxazepine of Example 16, Step A with 2,4-difluoro benzoylchloride of Example 9, Step A. Subsequent reaction of the intermediate (2,4-difluoro-phenyl)-(11H-5-oxa-4,10-diaza-dibenzo[a,d]cyclohepten-10-yl)-methanone with the sodium salt of 3-methylpyrazole in a manner analogous to that of Example 16, Step C will provide the title compound.
