Procedure

A mixture of cis-2,2,2-trifluoro-1-(8-hydroxy-2,3,4a,5,6,10b-hexahydro-1H-benzo[f]quinolin-4-yl)-ethanone (0.98 g), 4-methoxyphenylboronic acid (1.00 g), pyridine (1.30 mL), copper(II) acetate (0.60 g), molecular sieves 3 Å (3.60 g), and dichloromethane (15 mL) is stirred in air at room temperature overnight. The mixture is diluted with dichloromethane and filtered over Celite. The filtrate is concentrated and the residue is chromatographed on silica gel (dichloromethane/methanol containing 1% NH3 99:1→95:5) to give the title compound as a colorless resin-like solid. Yield: 1.05 g (79% of theory); LC (method 1): tR=5.00 min; Mass spectrum (ESI+): m/z=406 [M+H]+.
