Abstract

1,215,124. Thiobenzamides and their oxidation. OSTERREICHISCHE STICKSTOFFWERKE A.G. 10 Jan., 1969 [18 Jan., 1968], No. 1743/69. Heading C2C. The invention comprises novel thiobenzamides III of the formula wherein R is an alkyl group and R<SP>1</SP> is methyl or ethyl and their oxidation with hydrogen peroxide in an alkaline medium at a pH of not more than 11 to give the corresponding N,N- dialkyl - 3 - methoxy (or ethoxy) - 4 - hydroxybenzamides. The thiobenzamides III are obtained by treating with glacial acetic acid their dialkylamine salts, which are made by reacting 3-methoxy (or ethoxy)-4-hydroxybenzaldehyde in an anhydrous C 1-3 alkanol as solvent with more than 1 g. atom of sulphur and at least 4 moles of a dialkylamine of the formula at a temperature of 65‹ to 80‹ C.
