5-BROMO-1,3-DIMETHYLURACIL Use and Manufacturing

General procedure: A solution of bromo or chloro uracil (8.6 mmol) in dryethanol was added drop wise to an efficiently stirred solution of NaSH (20.8 mmol) in dry ethanol (50 mL) over a period of 2 h in ice cold condition. After the completion of addition, stirring was continued for an additional 4 h. Ethanol was removed under vacuum at room temperature. The residual mass was acidified with conc. HCl (25 mL). This was then extracted with CH2Cl2 (420 mL). DCM solution was washed with water (210 mL) and dried (Na2SO4). This DCM solution was directly used in the next phase-transfer catalyzed alkylation.
