Versuchsvorschrift

A solution of tetrahydro-N-hydroxymethyl-3-thiophenamine 1,1-dioxide hydrochloride of Example 3 (21.5 parts, 0.1 mole); 90 percent paraformaldehyde (3.7 parts, 0.11 mole); 70 percent aqueous orthophosphorous acid (12.9 parts, 0.11 mole); and water (6.0 parts) was heated at its reflux temperature for 3 hours. The product could not be isolated as a filterable solid due to its hygroscopic nature. The solution containing 61.9 percent of the title compound was used for testing without any further purification.
