Procedure

To 2.3 g. of 1,6-diaminohexane dissolved in 50 ml. of H2O was added dropwise with vigorous stirring a solution of 2 g. of S-methylthiopseudourea.H2SO4 in 20 ml. of H2O. After the completion of addition, the stirring was continued for 15 hours, after which the precipitate (the diadduct) was filtered. The filtrate was concentrated to a viscous oil which upon the addition of 50 ml. of MeOH precipitated 718 mg. of white powder.
