EXAMPLE - Mixture of 22.5 g 7-bromo-18-phenyl-17-azahexacyclo(18.2.1.0(2,19).0(3,16).0(4,9).0(10,15))tricosa-2(19),3,5,7,9,11,13,15,17-nonaene, 12.9 g of 1-napthylboron acid, 31.8 g of tripotassium phosphate, 224.5 mg of palladium(II) acetate, 1.8 g tri-ortho-tolyl phosphine, 200 ml of toluene, 50 ml of dioxane and 250 ml of water was stirred for 20 hours under reflux. After cooling, aqueous phase was separated and washed twice with 100 ml of water and once with 100 ml of saturated brine solution, and then filtered off over a bed of Celite (RTM: Diatomaceous earth) to remove palladium. After concentration, the residue was recrystallized five times from dimethylformamide and then twice under high vacuum and fractionally sublimed to obtain 11.2 g 7-(naphthalen-1-yl)-18-phenyl-17-azahexacyclo(18.2.1.0(2,19).0(3,16).0(4,9).0(10,15))tricosa-2(19),3,5,7,9,11,13,15,17-nonaene.
