Reaction Steps

To a homogeneous solution of 2-{3-methoxy-4-[(4-methoxybenzyl)oxy]benzyl}-3-morpholin-4-ylprop-2-enenitrile (14.5 g, 36.7 mmol) in isopropanol (050 mL) was added aniline hydrochloride (4.9 g, 37.5 mmol), and the mixture was stirred at reflux for 20 minutes, combined with 20 mL of water and cooled in an ice bath for 30 minutes. The resulting precipitate was filtered off, washed with water and air dried to give 13.7 g of crude product. This material was recrystalized from methanol/ethanol to afford pure product as a crystalline tan solid (10.5 g, 26.2 mmol). 1H NMR (300 MHz, d6-DMSO): δ 9.03 (d, J=12.8 Hz, 1H), 7.59 (d, J=12.8 Hz, 1H), 7.30 (d, J=8.6 Hz, 2H), 7.20 (d, J=7.4 Hz, 2H), 7.16 (m,2H), 6.93 (d, J=8.2 Hz, 1H), 6.88 (d, J=8.4, 1H), 6.86 (m, 1H), 6.83 (s, 1H), 4.90 (s, 2H), 3.69 (s, 3H), 3.68 (s, 3H), 3.50 (s, 2H), 3.28 (s, 2H). MS (ES-, m/z)=399 (M−H).
