| abstract | Title cpds. (I) (where Y is H or 1-4C alkyl and R is 1-4C alkyl), useful as fungicides (inters) are prepd. by reacting (II) (where X is halogen) with a cyanamide anion in the presence of an aprotic solvent at 0-200 degrees C to give a salt (III) (where M is an anion), reducing (III) and neutralizing the prod. to give (IV), reacting (IV) with 2 equivalents of ClCOOR in the presence of an acid acceptor in inert solvent at 10-100 degrees C to give (V), and converting (V) into (I) by reacting with a catalytic amt. of base at 10-150 degrees C. |
