Procedure

A suspension of 3.60 g (0.02 mole) of theophylline, 2.30 g (0.02 mole) of pyridine hydrochloride and 0.7 g (0.023 mole) of paraformaldehyde was heated at 80° for 24 hr. Upon cooling, crystals immediately formed in the solution. The crystals were filtered and dried in vacuo to give 4.83 g (28% yield) of the desired compound as its hydrate.
