Reaction Steps

In toluene, 7.9 g of 1-(5-bromo-n-pentyl)theobromine, 5.0 g of N-benzyhydrylpiperazine and 4 g of triethylamine are stirred under reflux for 30 hours. The subsequent treatments are carried out in the same manner as described in Example 96. The obtained crude crystal is converted to a hydrochloride according to customary procedures to obtain 4.7 g of intended 1-}5-[4-benzhydrylpiperazinyl-(1)]-n-pentyl}-theobromine hydrochloride (the yield being 40.9%).
