Versuchsvorschrift

The mesylate 17 (584 mg, 1.57 mmol) and 3-ethoxypropylamine (649 mg, 6.30 mmol) were dissolved in acetonitrile (30 mL). The mixture was then stirred at 75° C. under a N2 atmosphere overnight. After the confirmation of the disappearance of the mesylate by TLC, the solution was concentrated under reduced pressure. The residue was dissolved in CH2Cl2 (25 mL) and washed three times with aqueous sodium carbonate. The organic layer was separated, dried with anhydrous Na2SO4, filtered and concentrated under vacuum. Flash column chromatography of the residue gave 19 as a light yellow oil. Yield 60%; Rf=0.35 (0.5:4:85.5 NH4OH:MeOH:CH2Cl2); 1H NMR (CDCl3) δ 8.43 (d, 2H), 8.29 (s, 1H), 7.89 (d, 2H), 7.40 (m, 4H), 4.38 (s, 2H), 3.35 (q, 2H), 3.25 (t, 2H), 2.62 (q, 2H), 2.44 (t, 2H), 2.27 (t, 2H), 2.23 (t, 2H), 1.54 (q, 2H), 1.41 (q, 2H), 1.14 (m, 6H); 13C NMR (CDCl3) δ 131.3, 131.2, 130.6, 128.9, 127.2, 125.4, 125.0, 124.7, 69.1, 66.0, 50.7, 50.6, 48.2, 47.5, 47.2, 30.1, 27.1, 15.4, 11.9.
