Versuchsvorschrift

1.38 g of 50% sodium hydride suspended in oil were added under an inert gas atmosphere to a solution of 5.2 g of paraiodophenol in 30 ml of tetrahydrofuran and after stirring at 0° C., then 6.30 g of N,N-bis-(isopropyl)-2-bromo-acetamide (Preparation 8) were added. After stirring for 2 hours while allowing the temperature to rise to 20° C., the reaction medium was poured into ice-cooled water and filtration was carried out followed by drying to obtain 9.3 g of the expected product.
