Abstract
The condensation was generally carried out by heating an equimolecular mixture of the aldehyde and quinazolone. If the reaction was practically complete, the melt was purified by crystallization from alcohol, or some other suitable solvent, decolorizing with bone-black if necessary, while if the condensation was but a partial one, water was added, the excess of aldehyde driven out with steam, and the residue purified by crystallization.
