Методика

Aniline (16.8 mL, 184 mmol) is added to a solution of (S)-methyl 2-(methylsulfonyloxy)-2-phenylacetate (I5) (22.4 g, 92.0 mmol) in CH3CN (50 mL). The mixture is heated under MW irradiation at 120° C. for 5 minutes (UPLC-MS monitoring: complete conversion). The resulting crude is partitioned between EtOAc (200 mL) and 1N HCl (200 mL) and the aqueous phase is extracted with EtOAc (3×200 mL). The combined organic layers are dried over Na2SO4, filtered and evaporated under vacuum to obtain 20.3 g of a pale yellow solid (92% yield), which is used in the next step without any additional purification.
