Participants

Reaction Steps

3.5 g of 3-(4-piperidinomethylpyrazol-1-yloxy)propylamine and 3.6 g of 2-methylthio-5-(2-methylpyrid-5-ylmethyl)-1H-pyrimid-4-one in 30 ml of pyridine are refluxed for 30 hours. The pyridine is distilled off and the residue is then chromatographed over neutral Al2O3 (activity level III) using methylene chloride/3% strength methanol as the mobile phase. The oil obtained is reacted with tartaric acid in isopropanol to give an amorphous solid.
