Abstract: Method for preparing at least one phosphinopyridone (I) and/or its tautomer by preparing a solution of a phosphine and alkali metal in liquid ammonia; reaction with a pyridine compound (II) containing a protected hydroxy and a nucleophilically displaceable group to form a pyridine compound (III) with protected hydroxy and phosphine group, then deprotection to (I).
