実験手順

To 2′,4′-dihydroxy-3′-propyl acetophenone (3.0 g, 15.4 mmol) and 4-nitrobenzyl bromide (3.6 g, 17 mmol) in acetone (62 mL) is added K2CO3 (3.2 g, 23 mmol). The reaction mixture is refluxed for 1 h and cooled to room temperature. The precipitate is filtered, washed with water (5×70 mL), and dried to give the title compound (4.8 g, 94%). LC-MS (m/z): 328 (M−1).
