Methyl isothiocyanate → N-Methyl-N'-(2-{[(pyridin-4-yl)methyl]amino}ethyl)thiourea

Participants

Reaction Steps

Methylisothiocyanate (1.46 g.) was added slowly to a solution of N-(4-picolyl)ethylenediamine (3.3 g.) in ethanol (25 ml.) The mixture was heated under reflux for 0.5 hours concentrated and extracted with isopropyl acetate to remove N-4-picolyl-N,N'-dimethylethane-1,2-bis thiourea (m.p. 173°-4°). The mother liquors were concentrated and the residue purified by column chromatography to afford the title compound.
