Procedure

(4-Chloro-2-methyl-quinolin-7-yl)-methanol (example 2, 200 mg, 0.80 mmol) was refluxed in butylamine (2 mL) for 6 h. After cooling the reaction mixture was partitioned between sat. aq. ammonium chloride solution and dichloromethane. The organic layer was separated, dried (MgSO4), and evaporated. The residue was chromatographed (SiO2, CH2Cl2MeOH 19:1) to produce a yellow oil, which was heated in pyrrolidine (2 mL) at 70° C. for 16 h. After cooling the reaction mixture was partitioned between sat. aq. ammonium chloride solution and dichloromethane. The organic layer was separated, dried (MgSO4), and evaporated. Chromatography (SiO2, dichloromethane/methanol 19:1) afforded the title compound (108 mg, 43%). White solid, ISP-MS: m/e=312.3 ([M+H]+).
