Reaction Steps

A solution of the product of Example 9 (152 mg), methyl-phenethyl-piperidin-4-yl-amine (128 mg), and acetic acid (0.11 mL) in DCM (3 mL) was treated with sodium triacetoxyborohydride (190 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 (148 mg). 1H NMR (400 MHz, CDCl3): 7.29-7.25 (m, 2H), 7.21-7.16 (m, 5H), 6.83 (j, J=8.6 Hz, 2H), 3.99 (d, J=6.3 Hz, 2H), 3.41 (s, 2H), 2.92 (m, 2H), 2.77-2.66 (m, 4H), 2.47 (m, 2H), 2.40 (m, 4H), 2.34 (s, 3H), 2.00-1.88 (m, 4H), 1.71 (m, 2H), 1.62-1.55 (m, 6H), 1.44 (m, 2H).
