Reaction Conditions

Reaction Steps

To a suspension of the 4-amino-3-iodo-benzoic acid methyl ester from Step 1 (1.0 eq) in water (0.36M) was added NaNO2 (1.2 eq). The resulting mixture was cooled to 0° C. and aqueous HCl (6M; 2.5 eq) was added dropwise over 45 min. The mixture was stirred at 0° C. for 4 h, then NaN3 (1.1) dissolved in water (1.0M) was added over 30 min. The final mixture was stirred at room temperature for 1 h and extracted with Et2O (3×). The combined organic extracts were washed with brine, dried over MgSO4, filtered and concentrated. Flash chromatography (Hex:EtOAc; 4:1) afforded the desired compound as a light brown solid.
