関与物質

反応手順

Combine 6-(4-formyl-phenoxy)-nicotinamide (from step 1 above) (0.300 g, 1.24 mmol) and 1-benzylpiperazine (0.35 mL, 2.01 mmol) in methanol (12 mL) and stir at ambient temperature. After 15 h, add sodium borohydride (0.108 g, 2.85 mmol) and stir. After 1 h, filter the white precipitate and dry under vacuum to give 0.283 g (57%) of the title compound as a white solid: high resolution mass spectrum (electrospray): m/z calc for C24H27N4O2 403.2134, found 403.2128: 1H NMR (DMSO-d6): 8.63 (d, 1H, J=1.5 Hz), 8.27 (dd, 1H, J=2.4, 8.3 Hz), 8.05 (s br, 1H) 7.50 (s br, 1H), 7.39-7.23 (m, 7H), 7.15-7.06 (m, 3H), 3.48 (m, 4H), 2.41 (s br, 8H).
