Reaction Steps

Theophyllidine (hydrochloride), 27.0 g (0.142 mol), from step 1, was heated in 1400 ml methanol under reflux for 5 hours with acetylacetone, 28.7 g (0.284 mol), and 20 g concentrated hydrochloric acid. The solvent was then removed on the rotary evaporator and the yellow residue was purified by recrystallization from ethanol/diethyl ether.
