Use a method similar to the General Procedure 3 to couple 3-tert-butoxycarbonyl-6-trifluoromethanesulfonyloxy-2,3,4,5-tetrahydro-1H-benzo[d]azepine (0.6 g, 1.5 mmol) with 3-phenyl-1-propyne (0.38 mL, 3 mmol). Purify by chromatography on silica gel eluting with hexane/EtOAc (1:0, 40:1 and 20:1) to give 3-tert-butoxycarbonyl-6-(3-phenyl-prop-1-ynyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine as an orange oil (400 mg, 74%).
