Hydrochloric Acid → HCID 19873523, compound

Participants

Reaction Steps

1.15 g (28.8 mmol) of 60% sodium hydride was washed with n-hexane, and dry THF was added, and the mixture was cooled with ice. To this mixture, a THF solution containing 2 g (13 mmol) of N,N'-dimethyl-N'-methoxysulfamide was dropwise added. After stirring the mixture for 10 minutes, a dry THF solution containing 3.21 g (13.6 mmol) of phenyl N-chlorosulfonylcarbamate was dropwise added thereto. The mixture was stirred at room temperature for 7 hours. The reaction mixture was poured into 500 ml of ice water containing 3.5 g of 35% hydrochloric acid and extracted three times with diethyl ether. The diethyl ether layer was washed sequentially with water and a saturated sodium chloride aqueous solution and dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure to obtain 4.3 g of phenyl N-[(N-(N-methyl N-methoxyaminosulfonyl)-N-methylamino)sulfonyl]carbamate as slightly yellow oil.
