Reaction Steps

A mixture of crude 5-bromo-2-(2-fluoropyridin-3-yloxy)benzoic acid (8.00 g, 25.6 mmol), diethylamine (6.63 mL, 64.1 mmol) and TBTU (8.23 g, 25.6 mmol) in 8 mL of DMF was stirred overnight. The reaction was quenched with Sat. NaHCO3, extracted with EA/H=2:1, washed with brine, dried over Na2SO4, filtered and evaporated to dryness. CC (DCM to DCM/EA 100:5 to 100:10 to 100:20 to 3:1) gave 5-bromo-N,N-diethyl-2-(2-fluoropyridin-3-yloxy)benzamide as a yellow solid.
