Ethanol → 2-[2-(2-Dimethylaminomethyl-4-thiazolylmethylthio)ethyl]amino-5-(3-pyridyl)methyl-4-pyrimidone

Participants

Reaction Steps

A reaction mixture prepared from 1.24 g. of 2-nitroamino-5-(3-pyridyl)methyl-4-pyrimidone, 1.14 g. of 2-(2-dimethylaminomethyl-4-thiazolylmethylthio)ethylamine and 6 ml. of anhydrous ethanol was refluxed for about 1 day under a nitrogen atmosphere. The volatile constitutents were removed by evaporation to yield an oily residue. Water was added and the aqueous layer extracted with ether and with ethyl acetate. The organic extracts were combined, dried and evaporated to dryness to yield 2-[2-(2-dimethylaminomethyl-4-thiazolylmethylthio)ethyl]amino-5-(3-pyridyl)methyl-4-pyrimidone as a residue which was crystallized from ether. Recrystallization from an ethanol-ether solvent mixture yielded 2-[2-(2-dimethylaminomethyle-4-thiazolylmethylthio)ethyl]amino-5-(3-pyridyl)methyl-4-pyrimidone melting at 122°-123° C.; yield=0.68 g.
