Identify the major product of the following Hofmann elimination reaction: $[\text{cyclohexyl-}N^{+}(CH_3)(CH_2CH_3)(n\text{-Bu})]OH^{-} \xrightarrow{\Delta} \text{Major product}$

The major product formed by the reaction of benzylamine with nitrous acid is

$RCONH_2$ is converted into $RNH_2$ by means of Hofmann bromamide degradation. In this reaction,$RCONHBr$ is formed from which this reaction has derived its name. Electron donating group at phenyl activates the reaction. Hofmann degradation reaction is an intramolecular reaction.
