48% | With sodium carbonate; In methanol; for 2.5h;Reflux; | To a refluxing slurry of disodium carbonate (0.9 g. 0.01 mol) in 10 mL MeOH wasadded simultaneously a solution of 1,5-dichloropentan-3-one (0.93 mL, 0.01 mol) in 5 mL MeOH and a solution of <strong>[7149-75-9]4-chloro-3-methylaniline</strong> (1 g, 0.01 mol) in 5 mL MeOH dropwise over 10 mins. The reaction was allowed to reflux for a further 2.5 h, then allowed to cool and concentrated, poured into water (10 mL), and extracted with DCM (2 x lOmL). The combined organics were dried over MgSO4 and concentrated to yield 1.38 g free flowing orange/brown oil. The crude product was purified using column chromatography (Biotage, 50 g SNAP KP-SIL, 10 -80percent EtOAc in heptane, 10 CV) to yield the title compound as a light yellow free-flowing liquid (890 mg, 86percent purity, 48percent).1H NMR (500 MHz, Chloroform-d) delta 7.22 (d, J = 8.7 Hz, 1 H), 6.83 (d, J = 2.9 Hz, 1H), 6.74 (dd, J = 8.7, 3.0 Hz, lH), 3.56 (t, J = 6.1 Hz, 4H), 2.55 (t, J = 6.1 Hz, 4H), 2.35 (s, 3H).
