Sodium Bicarbonate → HCID 178468139, compound

Participants

Reaction Steps

3.4 g of 2-ethoxyethyl 4-hydroxyphenyl sulfide was dissolved in 50 ml of pyridine. 4-Guanidinobenzoyl chloride was added to the solution under cooling with ice and the mixture was stirred at room temperature for 27 h. A saturated aqueous solution of sodium hydrocarbonate was added thereto under cooling with ice. A precipitate thus formed was recovered by filtration, washed with water and then with acetone, and dried to obtain 2.86 g (yield: 40%) of 4-(2-ethoxyethylthio)phenyl 4-guanidinobenzoate carbonate.
