Procedure
To a 10 mL vial was added 1-cyclohexyl-N-(2,6-dichloro-5-quinolinyl)-cyclopropanecarboxamide (example 26 (b)) (0.13 g), N,N-dimethyl-1,3-propanediamine (0.13 mL) and acetonitrile (3 mL). The vial was sealed and heated at 100° C. in a microwave for 20 minutes followed by 30 minutes at 110° C. The solvent was removed from the cooled reaction under reduced pressure, saturated aqueous sodium hydrogen carbonate solution (30 mL) was added and the mixture was extracted with dichloromethane (3×50 mL). The combined organics were washed with water (50 mL) and brine (50 mL) before being dried, filtered and concentrated. Purification (Varian SCX cartridge, using methanol and 10% ammonia in methanol as eluant) gave a crude product which was further purified by chromatography (SiO2, ammonia:methanol:dichloromethane, 1:2.5:96.5 as eluant). The product was converted to its hydrochloride salt by dissolution in dichloromethane and treatment with 4M hydrogen chloride in 1,4 dioxane (5 mL). Removal of volatiles and recrystallisation from methanol/acetonitrile afforded the title compound (0.075 g).
