Procedure

Phenylmagnesiumbromide (1M in THF) (2eq) is added to a solution of 8 (50 mg) in THF (10 ml) at 78° C. under argon with stirring. The reaction is allowed to stir for 15 min. at 78° C. after the addition of Grignard at which time sat; aq. NH4Cl (4 ml) is added to quench the reaction. The mixture is diluted with EtOAc (60 ml) and water (2 ml), and the layers are separated. The organic layer is washed with sat. aq. NH4Cl (10 ml), water (10 ml), brine (10 ml), dried (Na2SO4), filtered and concentrated. The residue is purified by silica column chromatography eluting with EtOAc/hexane to give 13.
