Procedure
A stirred suspension of 2,6-dichloro-N-(cyclohexylmethyl)quinoline-5-carboxamide (Example 43(a)) (250 mg), (3S)-3-piperidinamine dihydrochloride (260 mg) and tetrabutylammonium bromide (20 mg) in acetonitrile (2 mL) was heated at 130° C. in a microwave for 90 minutes after which it was cooled to room temperature and concentrated. The residue was purified by chromatography (SiO2, dichloromethane:methanol:ammonia in methanol (7 M) 96:3:1 as eluant) and subsequent recrystallisation (acetonitrile) gave the title compound as a solid (120 mg).
