The mixture was stirred for 1 h at −10° C. and then heated to 0° C. Then 0.200 mL (0.200 mmol) phenylmagnesium bromide solution (1M in THF) were added, the mixture was stirred for 1 h and then heated to RT. The reaction mixture was combined with a saturated ammonium chloride solution and extracted with EtOAc. The combined organic phases were dried and evaporated down i. vac. The residue was purified by preparative HPLC-MS. The fractions containing the product were combined and evaporated down by half. The precipitate formed was suction filtered and dried.
