Procedure

Tris-(8-chlorocarbonyl-2,2,6,6-tetramethyl-benzo[1,2-d:5,4-d']-bis(1,3)oxathiol-4-yl)methanol (0.80 g, 0.80 mmol) was dissolved in benzene (200 mL). A solution of of bis(2-hydroxyethyl)amine (8.0 g, 48 mmol) in water (200 mL) was added and after vigorous stirring overnight, the mixture was transferred to a separatory funnel. The aqueous layer was removed and the remaining solid plus the benzene layer was evaporated, dissolved in methanol and passed through a short column (neutral alumina). After elution of unwanted materials with acetonitrile, the amide was eluted with methanol. After evaporation, the product was stirred with water (50 mL) at 40° C. for 2 h and then isolated by filtration. After drying, 0.60 g (60%) of the pure amide was obtained.
