実験手順

A mixture of ethyl 3-bromo-5-fluoro-1-(3-(naphthalen-1-yloxy)propyl)-1H-indole-2-carboxylate (The synthesis of this compound was described in EXAMPLE 134B as an intermediate) (404 mg), (E)-2-(5-chloropent-1-enyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (0.394 ml), diacetoxypalladium (19.28 mg), dicyclohexyl(2′,6′-dimethoxybiphenyl-2-yl)phosphine (70.5 mg) and K3PO4 (547 mg) was heated in a microwave reactor (CEM Discover) at 100° C. for 1 hour. The insoluble material was removed by filtration and the filtrate was concentrated. The residue was purified by flash chromatography, eluting with dichloromethane to provide the title compound.
