Versuchsvorschrift

A 120 mg sample of the compound from Example 9 above was dissolved in 4 mL of formic acid and 2 mL of formalin, and the reaction mixture was heated at reflux for 30 minutes. The reaction mixture was cooled to ambient temperature and poured into saturated K2CO3 solution. The resulting mixture was extracted with CH2Cl2, the extract was dried, and the solvent was removed. The residue was chromatographed on silica gel, and the compound was converted to the salt by treatment with HCl/ether: 1H NMR (D2O, 300 MHz) δ 2.30-2.40 (m, 3H), 2.50-2.74 (m, 1H), 2.98 (s, 3H), 3.45 (br d, 1H), 3.85 (br s, 1H), 4.97 (t, 1H), 7.47 (s, 1H), 8.08 (d, 1H), 8.51 (d, 1H), 9.10 (s, 1H); MS m/z: 203 (M+H)+ ; Anal. Calcd for C12H14N2O·2 HCl.0.5H2O: C, 50.70; H, 6.03; N, 9.86. Found: C, 50.69; H, 6.09; N, 9.61.
