Participants

Reaction Steps

Use a method similar to the General Procedure 8 to couple 2-chloro-pyridazine (98 mg, 0.86 mmol) with 3-tert-butoxycarbonyl-7-chloro-6-ethynyl-2,3,4,5-tetrahydro-1H-benzo[d]azepine (104 mg, 0.34 mmol). Purify by chromatography on silica gel eluting with isohexane/EtOAc (1:0 to 4:1 gradient over 30 min) to give 3-tert-butoxycarbonyl-7-chloro-6-pyridazin-2-ylethynyl-2,3,4,5-tetrahydro-1H-benzo[d]azepine (26 mg, 10%). MS (ES+) m/z: 384 (M+H)+.
