Versuchsvorschrift

3-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (3 g, 12.65 mmol) dissolved in dry THF was stirred with NaHCO3 (1.6 g, 19 mmol) and phenyl chloroformate (1.92 mL, 15.20 mmol) at room temperature overnight. The reaction mixture was partitioned between water and DCM, the organic layer recovered, dried over MgSO4, filtered and the solvent removed in vacuo, affording the title compound which was used without further purification.
