Compound that will give positive Lassaigne's test for both nitrogen and halogen is

Lassaigne's test gives presence of chlorine and nitrogen in organic compound by fusion of organic compound in the presence of sodium. The fused products in this case are:
${\mathrm{CH}}_3{\mathrm{NH}}_2.\mathrm{HCl}\underset{\mathrm{fusion}}{\overset{\mathrm{Na}}{\to }}\mathrm{NaCN} \mathrm{and} \mathrm{NaCl}$

$\mathrm{NaCN}$ gives +ve test for nitrogen and $\mathrm{NaCl}$ gives +ve test for halogen.
