Participants

Reaction Steps

A solution of 0.30 gram (8 millimoles) of sodium borohydride in 5 milliliters of water is added to a solution of 0.70 gram (3 millimoles) of 5-oxo-benzo[4,5]cyclohepta[1,2-b]pyrid-2(1H)one (prepared as described in Example I) in 50 milliliters of methanol and the resulting mixture heated for about twenty minutes at reflux temperature to obtain the desired 5-hydroxy-benzo[4,5]cyclohepta[1,2-b]pyrid-2(1H)one in the reaction mixture. The product is recovered by evaporating the solvent, and washing and drying the residue.
