Procedure
Dissolve 2,6-diaminopyridine (1.637 g, 15 mmol) in dioxane (15 mL) and cool to 0° C. for 10 min. Add 4-fluorobenzoyl chloride (793 mg, 0.59 mL, 5.0 mmol) slowly. After 40 min, remove ice bath and stir the reaction at room temperature. Use the work-up and purification procedures described in Preparation 43 to provide N-(6-Amino-pyridin-2-yl)-4-fluoro-benzamide as a slightly yellow solid (1.170 g, 100%): mass spectrum (ion spray): m/z=232.0 (M+1).
