    • The present invention provides an improved method of making 1-(alkoxyphenyl)-5-(phenyl)biguanide compounds which are useful as agricultural fungicides, having the formula: ##STR1## where R is alkyl, linear of branched, having from 1-14 carbon atoms; and acid addition salts thereof.The method comprises the steps of (a) alkylating a nitrophenol with a suitable alkyl halide in a reaction solvent to form an alkoxynitrobenzene intermediate, (b) reducing the nitro group of the itermediate in situ by catalytic hydrogenation to form an alkoxyaniline, and (c) condensing the alkoxyaniline with phenyldicyandiamide to form the desired biguanide as the acid addition salt.The invention also includes a novel isolation and purification procedure for obtaining purified biguanide acid addition salts and purified free biguanide base.
