Reaction Steps

A mixture of 5,7-diazaspiro[2.5]octane-6-thione (7.53 g; 0.053 mol), methyl iodide (8.43 g; 0.0594 mol) and absolute ethanol (26 ml) is stirred and heated at 45° C. for one hour until the reaction mixture becomes straw colored and homogeneous. Ethyl acetate is added with cooling, the precipitated crystalline material is collected and dried to afford 14.05 g (93.5% yield) of title product, m.p. 128°-130° C.
