Reaction Steps

A mixture of 6-chloro-4-phenyl-3-trifluoromethyl-pyridazine (D3) (0.10 g, 0.39 mmol), octahydro-pyrrolo[1,2-a]pyrazine, racemic mixture, (0.053 g, 0.42 mmol) and diisopropylethylamine (0.103 ml, 0.585 mmol) in acetonitrile (3 ml) was stirred at 150° C. for 30 min., under microwave irradiation. The reaction mixture was then diluted with dichloromethane (25 ml) and extracted with a saturated solution of sodium carbonate (12 ml). The organic layers were separated, dried (Na2SO4), filtered and the solvent evaporated in vacuo. The residue was then purified by column chromatography (silica gel; 0-2.5% ammonia in methanol (7M)/dichloromethane). The desired fractions were collected and evaporated in vacuo. The residue was precipitated from acetonitrile/heptane. The product obtained was treated with a solution of hydrochloric acid in diethyl ether (2M) to yield the corresponding salt E5 (0.081 g, 54%) as a white solid. C18H19F3N4.HCl; free base requires 348; Found 349 (MH+).
