To a solution of 4-borono-2-fluorobenzoic acid (1.0 g, 5.43 mmol) and HATU (2.0 g, 5.43 mmol) in DMF (20.0 mL) was added morpholine (0.9 g, 10.87 mmol) at room temperature. The reaction mixture was stirred at room temperature for 18 h. The reaction mixture was poured into ice cold water, acidified with 1N HCl, extracted with EtOAc (2×50 mL). The organic layer was washed with brine solution (20 mL), dried over anhydrous Na2SO4 and solvent was evaporated under reduced pressure to afford 1.2 g of crude compound as a colourless gum. Crude compound was directly used for the next step without any further purification.
