85% | Stage #1: With potassium carbonate; potassium hydroxide In acetonitrile at 80℃; for 0.166667 h; Stage #2: at 80℃; for 2 h; |
A mixture of 4-diethylamino-2-hydroxy benzaldehyde (5.8 g,30 mmol), KOH (2 g, 35 mol) and K2CO3 (8.3 g, 60 mmol) inacetonitrile (30 ml) was heated for 10 min at 80 °C. MeI (3.5 ml,56 mmol) was added to this alkaline mixture and stirring wascontinued for another 2 h at 80 °C. The reaction mixture was thencooled to room temperature filtered. The filtrate was concentratedunder reduced pressure and chromatographed on silica gel column(mesh sizee120-200) eluting with EtOAc/hexane in 1:3 ratio to get pure compound as yellow solid (yield 85percent).1H NMR (500 MHz, CDCl3) δ 10.11 (s, 1H), 7.68 (dd, J 8.9, 2.8 Hz,1H), 6.26 (d, J 8.8 Hz, 1H), 6.02 (s, 1H), 3.87 (s, 3H), 3.41 (dd,J 6.9, 2.7 Hz, 4H), 1.21 (t, J 5.4 Hz, 6H).13C NMR (125 MHz, CDCl3) δ: 187.1, 164.1, 153.8, 130.7, 114.2,104.2, 92.4, 55.2, 44.7, 12.5 (see Fig. 2). |
