Versuchsvorschrift

1-(Benzo[d][1,3]dioxol-5-yl)-N-(5-(hydroxy(2-methoxyphenyl)methyl)pyridin-2-yl)cyclopropanecarboxamide (41.8 mg, 0.100 mmol) was suspended in 2 mL of toluene containing 4-methylbenzenesulfonic acid hydrate (pTsOH, 23.8 mg, 0.125 mmol) and propane-1,3-diol (9.89 mg, 0.130 mmol). The reaction mixture was then heated to 140° C. for 5 minutes in a microwave reactor. The crude product was then filtered, evaporated to dryness, dissolved in N,N-dimethylformamide (1 mL) and purified by reverse-phase preparative liquid chromatography utilizing a gradient of 0-99% acetonitrile in water containing 0.05% trifluoroacetic acid to yield the pure product (26.5 mg, 0.0556 mmol, 55.6%). ESI-MS m/z calc. 476.5. found 477.3 (M+1)+. Retention time 2.71 minutes.
