Versuchsvorschrift

A solution of the product of Example 9 (214 mg), [2-(3,4-dimethoxy-phenyl)-ethyl]-methyl-amine (170 mg), and acetic acid (0.05 mL) in DCM (3 mL) was treated with sodium triacetoxyborohydride (300 mg). After 16 h, the resulting mixture was treated with 10% sodium hydroxide (5 mL) and extracted with DCM (3×10 mL). The combined organic phases were dried (sodium sulfate) and evaporated. Chromatography of the residue (1-5% 2 M methanolic ammonia/DCM) gave the title compound as a colorless oil (350 mg). 1H NMR (400 MHz, CDCl3): 7.18 (d, J=8.6 Hz, 2H), 6.85-6.69 (m, 5H), 3.99 (t, J=6.3 Hz, 2H), 3.85 (s, 6H), 3.48 (s, 2H), 2.79-2.74 (m, 2H), 2.63-2.58 (m, 2H), 2.50-2.35 (m, 6H), 2.25 (s, 3H), 1.97 (m, 2H), 1.63-1.56 (m, 4H), 1.47-1.40 (m, 2H).
