Diazotisation of aniline derivatives I want to know if N-methyl aniline $(\ce{PhNHCH3})$ can undergo diazotisation under suitable conditions and in the presence of $\ce{NaNO2}/\ce{HCl}.$

The mechanism involves loss of two $\ce{H+}$ during the formation of the diazo compound, but if we have one $\ce{CH3}$ and one $\ce{H}$ instead of two $\ce{H}$ (as we have for aniline), will the $\ce{CH3+}$ act as a good leaving group? Is diazotisation of $\ce{PhNHCH3}$ feasible?
Secondary amines react with nitrous acid to give N-nitroso compounds reference here

N-Methylaniline will give N-Methyl-N-nitrosoaniline as shown below
