Abstract

PURPOSE: To prepare the title compound useful as pesticides and medicines readily and quantitatively under very mild conditions, by reanranging a 2-methoxybenzthiazolone derivative in the presence of a tertiary amine or its salt under heating.
CONSTITUTION: A 2-methoxybenzthiazole denivative of formula I: (R is H, halogen, or lower alkyl group) is reanranged in the presence of a tertiary amine, preferably a relatively strong base, e.g. an aliphatic tertiary amine, 1,5-diazabicyclo [3,4,0]nonene-5, or 1.5-diazabicyclo [5,4]undecene-5, or its salt, e.g. hydrochloride, hydrobromide, or sulfate, under heating to give the desired N-methylbenzthiazolone devivative of formula II. The reaction may be carried out at a temperature 5W10°C higher than the melting point of the objective compound in the absence of a solvent, and near the reflux temperature of the solvent in the presence of an organic solvent, e.g. a tertiary amine.
