Add a solution of 3-cyanobenzoyl chloride (553 mg, 3.34 mmol) in dichloromethane (10 mL) to a solution of 1-[4-(3-amino-benzyloxy)-2-hydroxy-3-propyl-phenyl]-ethanone (1.00 g, 3.34 mmol) in dichloromethane (10 mL), and triethyl amine (1.4 mL) at 0° C. Stir to room temperature for one hour. Partition the mixture between dichloromethane (20 mL) and 2N hydrochloric acid (30 mL). Wash the organic layer with 2N hydrochloric acid (20 mL), saturated sodium bicarbonate, brine, dry, filter, and concentrate to afford the title compound as a light yellow powder (1.33 g, 93%): 1H NMR (CDCl3) δ 0.96 (t, 3H), 1.59 (sextet, 2H), 2.55 (s, 3H), 2.72 (t, 2H), 5.19 (s, 2H), 6.47 (d, 1H), 7.26 (d, 1H), 7.42 (t, 1H), 7.54-7.59 (m, 2H), 7.65 (t, 1H), 7.77 (s, 1H), 7.84 (d, 1H), 7.88 (s, 1H), 8.11 (d, 1H), 8.17 (s, 1H), 12.75 (s, 1H).
