Sodium hydride (60% disp. in mineral oil, 240 mg, 6 mmol) was added to a stirred solution of 1,1-dimethylethyl 7-hydroxy-8-iodo-1,2,4,5-tetrahydro-3H-3-benzazepine-3-carboxylate (D41) (1.94 g, 5 mmol) in dimethyl sulfoxide (10 ml). After 10 minutes, 6-chloro-N-methyl-nicotinamide (D10) (850 mg, 5 mmol) was added and the reaction mixture was heated to 100° C. for 20 hours. After cooling to room temperature the reaction mixture was diluted with water and dichloromethane. The organic layer was separated, washed with water and brine, dried over magnesium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography (1:1 ethyl acetate:hexanes) to afford the title product (D42).
