VI1 9-bromotoluene the situation is reversed, substitution occurring chiefly adjacent to the bromine atom in the ratio 1.8: 1.* For the purpose of the present synthesis a separation (or distillation) is not required, and 4-chloro-7-methylhydrindene (VI) was obtained in 95% yield from the mixture of hydrindones. For the preparation of the ketone VI11 the chloro compound VI was first converted into the nitrile VI1 by the Rosenmund-von Braun method. Fairly ...
