Phosphorylation of N-alky lated imidazoles and benzimidazoles at C-2 by CH3POCl2, PhPOCl2-POCl3 in pyridine-triethylamine solution is described. The formed heteroaryl-substituted phosphinic or phosphonic acid chlorides were transformed without isolation into the corresponding phosphinic (phosphonic) acids, their salts or amides with moderate yields This reaction opens a simple way to potential haptens derived from
