${CH}_{3} NC \to_{(ii) H_{3} O^{+}}^{(i) {LiAlH}_{4}} \underset{2 ° amine}{{CH}_{3} {NHCH}_{3}}$

${CH}_{3} CN \to_{(ii) H_{3} O^{+}}^{(i) {LiAlH}_{4}} \underset{1 ° amine}{{CH}_{3} {CH}_{2} {NH}_{2}}$

${CH}_{3} {CONH}_{2} \overset{{Br}_{2} / KOH}{\to} \underset{1 ° amine}{{CH}_{3} {NH}_{2}}$

${CH}_{3} {CONH}_{2} \to_{(ii) H_{3} O^{+}}^{(i) {LiAlH}_{4}} \underset{1 ° amine}{{CH}_{3} {CH}_{2} {NH}_{2}}$
