Participants

Reaction Steps

3,4-Dihydro-4-amino-2,2-dimethyl-6-(nonafluorobutyl)sulfonyl-2H-1,4-benzoxazine (0.46 g) was dissolved in 5 ml of pyridine, followed by the dropwise addition of 0.12 ml of methyl chloroformate under ice cooling and stirring. After the reaction mixture was stirred for 15 hours at room temperature, the reaction mixture was added with 10% hydrochloric acid and then extracted twice with chloroform. The combined chloroform layer was washed with water and with saturated brine and was then dried over magnesium sulfate. The solvent was distilled off and the residue was purified by chromatography on a silica gel column, whereby 0.77 g of Compound No. 53 was obtained (yield: 70 %).
