Participants

Reaction Steps

Following the procedure described in Step 6, of Example 1, the title compound was prepared from [6-(5-Chloro-3-pentanoyl-benzofuran-2-yl)-naphthalen-2-yloxy]-acetonitrile (0.31 g, 0.74 mmol), sodium azide (0.325 g, 5 mmol) and ammonium chloride (0.268 g, 5 mmol) in DMF (20 mL). Trituration with methanol afforded the title compound as a yellow solid (0.26 g), mp 178-180° C. Mass spectrum (+APCl, [M+H]+) m/z 461. 1HNMR (400 MHz, DMSO-d6): δ8.4 (s, 1H), 8.07-7.99 (m, 3H), 7.85 (dd, 1H, J=8.5, 1.7 Hz), 7.77 (d, 1H, J=8.8 Hz),), 7.64 (d, 1H, J=2.2 Hz),), 7.48 (dd, 1H, J=8.8, 2.2 Hz),), 7.38 (dd, 1H, J=8.8, 2.4 Hz), 5.66 (s, 2H), 2.70 (t, 2H, J=7.4 Hz), 1.56-1.48 (m, 2H), 1.15-1.06 (m, 2H), and 0.69 ppm (t, 3H, J=7.5 Hz). Elemental Analysis for C25H21ClN4O3.0.5H2O: Calculated: C, 64.52; H, 4.66; N, 12.04. Found: C, 64.40; H, 4.42; N, 12.07.
