実験手順
When isobutyraldehyde was reacted under conditions similar as described in Example I, above, for the preparation of dihydrothiazoles from ketones, no incorporation of sulfur occurred. However with a variation in the reaction, secondary aldehydes could be made to yield dihydrothiazoles in excellent yield. The reaction of isobutyraldehyde with ammonia yielded, via an intermediate, 2,6-dimethyl-4-azahepta-2,4-diene.
