Procedure

3-(3-Aminopropoxy)-N,N-dimethylbenzenemethanamine (10 g) and 1,1-bis-(methylthio)-2-nitroethane (16 g) were heated under reflux in tetrahydrofuran for 19 hours. Oxalic acid dihydrate (1.3 g) was added and the resulting precipitate was discarded. The solvent was removed to leave the title compound as a crystalline solid (10 g) m.p. 59°-63°.
