Compound 83 (15 mg, 0.044 mmol) was dissolved in dry THF (0.8 mL) and this solution added to the phenyl magnesium bromide (1M, 0.2 mL, 0.20 mmol) at 0° C. The mixture was stirred and allowed to warm slowly to RT. The mixture was quenched with MeOH/HCl (2M) (1 mL:0.1 mL) then NH4Cl (sat.) added and the mixture diluted with water and EtOAc (pH of aqueous ˜7). The mixture was extracted into EtOAc and the organics combined and dried with brine then Na2SO4. The solvent was removed to afford 20 mg crude residue. This was dissolved in DCM (2 mL) and applied to a silica column, eluting with EtOAc/heptane, to afford Compound 112 (13 mg).).
