Procedure

A mixture of 4-bromo-1-fluoro-2-nitrobenzene (I-9, Aldrich, Wis.; 25 g, 0.11 mol) and 2-aminoethanol (13.9 g, 0.23 mol, 2.0 eq.) in n-butanol (300 mL) was heated under reflux for 1 hour. The reaction mixture was concentrated and the residue was dispersed in petrol ether (600 mL) and stirred overnight. The solids were iltered to give I-10 as a yellow powder (29 g, 98%). MS (ESI): m/z 262 (M+H+).
