Reaction Steps

A mixture of 6-(4-aminophenyl)-5-methyl-4,5-dihydro-1,2,4-triazin-3(2H)-one (2.04 g), 1,4-dibromobutane (2.59 g), potassium carbonate (0.35 g) and potassium iodide (0.5 g) in DMF (10 ml) was heated at 80° C. for 5 hours under stirring, and then evaporated in vacuo. After addition of 30% aqueous methanol to the residue, the resulting precipitates were collected by filtration and recrystallized from a mixture of methanol and chloroform (7:3) to give 6-(4-pyrrolidinophenyl)-5-methyl-4,5-dihydro-1,2,4-triazin-3(2H)-one (0.65 g).
