Versuchsvorschrift

To a solution of 4-acetamidophenol (7.56 g, 50 mmol) in DMF (20 ml) was added 60% NaH (2.2 g) followed by 5-chloro-2-nitroaniline (9.06 g, 50 mmol). The mixture was heated to 120° C. overnight. After cooling, 800 ml of water was added and the resultant solid was collected by filtration. Desiccation in vacuo gave intermediate 1 as a brown solid (13.75 g, 96%): MS m/e 286 (M−1).
