実験手順

2.53 g (11 mmol) of the compound from Example 4A were initially charged in 50 ml of absolute tetrahydrofuran (THF). At 20° C., 3.07 ml of triethylamine were added dropwise, the mixture was stirred for 5 min and 2.44 g (10 mmol) of (4′-fluoro-4-methylbiphenyl-3-yl)acetic acid were added. After 15 min, a further 2.3 ml of triethylamine were added, followed immediately by the dropwise addition of 0.58 ml (6.2 mmol) of phosphorus oxychloride, and the mixture was stirred under reflux for 30 min. The mixture was concentrated under reduced pressure and the residue was purified by means of flash chromatography on silica gel using the mobile phase n-hexane/ethyl acetate 1:1. This gave 2.84 g (60% of theory) of the title compound of melting point 187° C.
