実験手順

To 4-Hydroxy benzaldehyde (10 g) in acetone (200 ml), potassium carbonate (16.96 g) was added and stirred. To this, benzyl bromide (12.67 ml) was added and the reaction mixture was refluxed for 3 hours and then cooled. The reaction mixture was filtered and the filtrate was concentrated to obtain pale brown colored oil which got solidified at room temperature. Solid was crystallized from DCM-Petroleum ether to obtain the title compound as pale yellow solid. Yield: 13 g (74%); 1HNMR (CDCl3; 300 MHz): δ 9.91 (s, 1H), 7.87 (d, 2H), 7.33-7.43 (m, 5H), 7.12 (d, 21-1) 5.17 (s, 2H).
