Procedure

Methylaminoacetaldehyde dimethylacetal (3.7 grams, 0.031 mole) was added to a 50 milliliter benzene solution containing 3.7 grams (0.031 equivalent) of the 5-[1-(3-methylphenoxy)ethyl]-1,3,4 -thiadiazol-2-yl isocyanate dimer (prepared above) and the resulting solution was refluxed for 15 minutes and then cooled. Hexane (100 milliliters) was added and the resulting solution formed crystals which were filtered off, and dried in a vacuum oven at 80° C. to 9.0 grams of white crystals of [5-[1-(3-methylphenoxy)ethyl]-1,3,4-thiadiazol-2-yl]-1-methyl-1-(2,2-dimethoxyethyl)urea (melting point 122°-125° C.).
