Procedure

To a solution of 4-chloroaniline (5.0 g, 39.2 mmol) in 25 mL pyridine was added 5.3 mL (43.1 mmol) of pivaloyl chloride and the reaction mixture stirred overnight at room temperature. The mixture was poured into vigorously stirring 6M HCl, and the solids were collected by vacuum filtration, washed well with H2O, and dried in vacuo to yield the title compound. 1H NMR (CDCl3) δ 7.47 (d, J=9.2 Hz, 2H) 7.30 (s, 1H) 7.27 (d, J=8.8 Hz, 2H) 1.32 (s, 9H) MS (ES) m/z=212.1
