Reaction Steps

A mixture of EXAMPLE 31B (1.08 g), ortho-tolylboronic acid (1.1 g), (1,1′-bis(diphenylphosphino)ferrocene)dichloropalladium(II) (140 mg) in dimethoxyethane:2N aqueous Na2CO3 (25 mL:5 mL) was stirred under nitrogen at 80° C. for 16 hours, diluted with ethyl acetate and was washed with water and brine. The organic phase was dried (MgSO4), filtered, and concentrated. The concentrate was purified by flash chromatography on silica gel with 0-10% ethyl acetate/hexanes.
