Compound L (40g, 0.12mo1), carbamte (24.18 0.14mop, capper (3.3g, O.OSmop, 18-crown-6 (2.3g, 0.009mop, and K,_CQ, (66.38 0.48mo1) were added to the two-neck flask and an argon atmosphere was established in a vacuum. 7,2-dichloroben7ene (250mp was added and the mixture was stirred under reflex at 180C for 6 hours. Upon completion of the reaction, copper was removed by using Celite filter and the reaction mixture was dissolved with MC. After removing a solvent. Pure Compound M (36g, (81 %) was separated by column chromatography using dichtoromethane and hexane as an eluent.
