Reaction Steps

Under N2 atmosphere, in an ampoule 1.8 g (12.7 mMol) of trans 4-isopropyl-cyclohexylamine (preparation see Arzneim. Forsch. 1969, 19, 140) and 700 mg (2.4 mMol) of 1-chloro-4-[6-methoxy-pyridin-3-yl)methyl]phthalazine are heated during 14 h at 140° C. The suspension is dissolved by dilution with EtOAc, 1.5 ml of NH3 solution (25%) and water, and the aqueous phase is removed and extracted twice with EtOAc. The organic phases are washed with water and brine, dried (Na2SO4) and evaporated. Crystallization from EtOAc/hexane 1:1 results in the title compound: M.p. 124-125° C.; FAB-MS: (M+H)+=391; HPLC(Grad20-100) tRet12.4.
