Benzenesulfonyl chloride, 2,4-dimethyl- → (1R,6S)2-[3-(2,4-Dimethyl-benzenesulfonyl)-3,8-diaza-bicyclo[4.2.0]oct-8-yl]-quinoxaline

Participants

Reaction Steps

The title compound was prepared in a manner analogous to Example 19, substituting (1R,6S)-2-(3,8-diaza-bicyclo[4.2.0]oct-8-yl)-quinoxaline (Intermediate 3) for 8-(4-phenyl-pyrimidin-2-yl)-3,8-diaza-bicyclo[4.2.0]octane and 2,4-dimethyl-benzenesulfonyl chloride for 2,5-dimethyl-benzenesulfonyl chloride.
