Abstract
Method of preparation of 3-methoxymethyl-1- (5-nitrofurfurylidene-amino) hydantoin, represented by the formula: ** (See formula) ** comprising: a) the reaction of 1-aminohydantoin with an alkali metal hydride in the presence of an inert reaction medium) b) the addition of a halomethyl methyl ether to said reaction medium and heating of the mixture until the reaction is complete) and c) separating volatiles from said reaction medium to give a residue which is dissolved in aqueous mineral acid and treated with a member of the group consisting of 5-nitrofurfural and derivatives thereof, hydrolyzable therein.
