3 NH4OH be complete. In a similar manner and with an arbitrary reduction time of 11 h, the resulting crude solution of homophthalaldehyde was treated with aqueous ammonium hydroxide (30 equiv), After 5 h, amination was found to be essentially complete. When these conditions were applied to the conversion of indene to isoquinoline, consistent isolated yields of 73-82% were obtained. Other variants in the reaction condit, ions such as ...
