Reaktionsschritte
16.7 g of mercaptobenzothiazole, 3.0 g of paraformaldehyde, 15.4 g of 2,6-dimethoxyphenol and 1 g dibutylamine are heated at 110°, with rapid stirring, for 2 hours. 50 ml of ethanol are added and the mixture cooled to 10° thereby obtaining 27.3 g of 3-(3,5-dimethoxy-4-hydroxybenzyl)-benzothiazole-2-thione (compound No. 8) melting at 141°-142°.
