Supplement the equation: CH3COOH – X – aminoacetic acid – (CH3) 2NCH2COOH

Supplement the equation: CH3COOH – X –  aminoacetic acid – (CH3) 2NCH2COOH and the reaction of conversion of aminoacetic acid to methylamine

Let us write down the reaction equations for the transformation chain:
CH3COOH + Cl2 = CH2Cl – COOH + HCl – substitution reaction, chloroacetic acid is released;
CH2Cl – COOH + 2NH3 = NH2 – CH2 – COOH + NH4Cl – exchange, aminoacetic acid was obtained;
Getting methylamine:
CH3COOH + NH3 = CH3 – COO – NH4 = CH3 – CO – NH2 + H2O – the interaction of acetic acid with ammonia on heating leads to the formation of acetylamide;
CH3 – CO – NH2 + H2O + HCl = CH3COOH + NH4Cl – hydrolysis in an acidic medium, acetic acid obtained;
CH3COOH + CH3 – NH2 = CH3 – CO – NH – CH3 + H2O – acetic acid reacts with methylamine to form acetic acid methylamide;
CH3 – CO – NH – CH3 + NaOH = CH3 – COONa + CH3NH2 – exchange, methylamine is released.
Methylamine is called glycine in medicine, which is involved in protein biosynthesis and is used as a medicine.
