Reaction Steps

A mixture of 3-(8,9-dihydroxynonyl)-1-methyluracil (2.15 g, 7.6 mmol) and a 30% solution of hydrogen bromide in acetic acid (4.5 mL, 23 mmol) were stirred for 6 hours. The reaction mixture was added slowly to a mixture of sodium bicarbonate (8.4 g, 0.1 mol), water (30 mL), and dichloromethane (30 mL). The layers were separated, and the aqueous layer extracted with dichloromethane (3×40 mL). The combined organic layers were washed with aqueous saturated salt solution (20 mL) and dried over sodium sulfate. The solvent was removed under vacuum to yield 2.89 g (97% yield) 3-(8-acetoxy-9-bromononyl)-1-methyluracil (inventive compound no. 1801) as a thick, slightly orange oil.
