To a dry toluene solution of [1-Iodo-cyclopropylsulfanyl]-benzene (375 mg, 1.36 mmol) was added 6-Hydroxy-1-methyl-3,4-dihydro-1H-quinolin-2-one (200 mg, 1.13 mmol) and silver carbonate (312 mg, 1.13 mmol) under nitrogen and the reaction mixture was heated to 55° C. It took 3 more additions of the reagents to take the reaction to completion. The reaction was cooled to room temperature, filtered to remove the silver iodide and concentrated under vacuum to yield crude material. This was flash chromatograhed using 30% ethyl acetate/hexane to yield the title compound as a viscous oil (64 mg, 17% yield). 1H NMR (400 MHz, CDCl3) δ 1.31–1.33 (2H, m), 1.41–1.43 (2H, m), 2.59–2.62 (2H, m), 2.83–2.87 (2H, m), 3.31 (3H, s), 6.86–6.98 (4H, m), 7.20–7.31 (2H, m), 7.44–7.47 (2H, m). m/z (APCI+) 326 (M+1). HPLC (aqueous 200 Mm ammonium acetate buffer/acetonitrile gradient, 3.0 ml/min, Hewlett Packard ODS Hypersil 5 μM, 125×4 mm column), 6.59 minutes.
