Vorschrift

A solution of the product of Example 9 (277 mg), aniline (108 mg), and acetic acid (0.07 mL) in DCM (5 mL) was treated with sodium triacetoxyborohydride (340 mg). After 16 h, the resulting mixture was treated with 10% sodium hydroxide (10 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 (256 mg). 1H NMR (400 MHz, CDCl3): 7.27 (m, 2H), 7.18 (m, 2H), 6.88 (m, 2H), 6.72 (m, 2H), 6.64 (m, 2H), 4.24 (s, 2H), 4.00 (t, J=6.6 Hz, 2H), 3.94 (br, 1H), 2.48 (m, 2H), 2.41 (br, 4H), 1.98 (m, 2H), 1.64-1.57 (m, 4H), 1.48-1.41 (m, 2H).
