Reaction Steps
In analogy to the procedure for Example 1, 200 mg (0.66 mmol) crude N-[1-(3-cyclopentyl-5-oxo-4,5-dihydro-1,2,4-triazin-6-yl)propyl]-2-methylcyclopropanecarboxamide, 165 mg (1.1 mmol) phosphoric trichloride are stirred at reflux for 4 hours, proportionate amounts of the solvents are used. The isomers are purified by chromatography (preparative HPLC).
