Procedure
Diisopropylazodicarboxylate (97 mg, 0.48 mmol) was added dropwise at r.t. to a solution of (4-chloro-2-methyl-quinolin-7-yl)-methanol (example 2c, 100 mg, 0.48 mmol), triphenylphosphine (126 mg, 0.48 mmol), and 4-fluorophenol (54 mg, 0.54 mmol) in dichloromethane (2.5 mL). After shaking 24 h at r.t., the solvent was evaporated, and the residue was taken up in pyrrolidine (1.37 g, 19.2 mmol) and shaken for 23 h at 80° C. After cooling the reaction mixture was partitioned between sat. aq. ammonium chloride solution and dichloromethane, the organic layer was washed with brine, dried (MgSO4), and evaporated. Chromatography (SiO2, dichloromethane/methanol 19:1) yielded the title compound (66 mg, 41%). Off-white solid, ISP-MS: m/e=337. ([M+H]+).
