Participants

Reaction Steps

To a mixture composed of 16 g of Compound [1-g] and 70 ml of pyridine was added dropwise 13 g of benzenesulfonyl chloride under cooling with ice. The mixture was stirred at a temperature range between 10° C. and 15° C. for 2 hours and then the reaction solution was poured into cold diluted hydrochloric acid. The precipitate thus deposited was collected by filtration, washed with water and recrystallized from acetonitrile to obtain 9.5 g of Compound [1-h].
