Reaction Steps
2-methyl benzothiazole (19.5g, 0.1M) and 6-bromohexanoic acid (15.3g, 0.1M) were mixed and heated at 120° C. for 4 hours under continuous agitation. The resulting solid was broken up, ground with ether and then filtered. The filtrate was washed with more ether (250ml) to yield an off-white powder (57.5g).
