Participants

Reaction Steps

To a solution of 0.85 gram (0.0034 mole) of the N-oxide thus obtained and 0.77 gram (0.0043 mole) of tosyl chloride in 37.5 milliliters of chloroform was added a solution of 0.58 gram (0.0042 mole) of potassium carbonate in 5.8 milliliters of water and the resulting mixture was stirred vigorously at room temperature for two days and the reaction mixture washed with alkali to obtain an 11-oxo-5,6-dihydrobenzo[5,6]-cyclohepta[1,2-b]pyrid-2(1H)one product which is recovered and purified by conventional procedures.
