Reaktionsschritte

A mixture of 2.5 g methyl 4-acetylamino-5-chlorosalicylate, 2 g of 3-bromocyclohexene, 2 g K2CO3 and 30 ml DMF are combined and heated at 110° C. overnight. The reaction mixture is then poured into water, filtered, dried and then extracted into ether. The ether solution is treated with charcoal, filtered and evaporated to dryness to obtain methyl 2-(cyclohexen-3-yloxy)-4-acetylamino-5-chlorobenzoate. This is then purified by recrystallization from ether/hexane. (M.P. 100°-102° C.)
