Reaction Steps

A solution of 54.4 mg (0.119 mmol) ethyl 2-fluoro-4-[[(5,6-dihydro-5,5-dimethyl-8-(4-methylphenyl)-2-naphthalenyl)carbonyl]amino]-benzoate (Compound 40) and 57.7 mg (0.143 mmol) of [2,4-bis(4- methoxyphenyl)-1,3-dithia-2,4-diphosphetane-2,4-disulfide] (Lawesson's Reagent) in 12.0 ml of benzene was refluxed overnight. Upon cooling to room temperature, the mixture was filtered and the filtrate concentrated under reduced pressure. The title compound was isolated by column chromatography (10 to 25% EtOAc/hexanes) as a yellow solid. 1H NMR (CDCl3): δ 9.08 (1H, s), 7.92 (1H, br s), 7.90 (1H, t, J=8.2 Hz), 7.66 (1H, dd, J=2.0, 6.0 Hz), 7.38 (3H, m), 7.18 (4H, m), 6.01 (1H, t, J=4.7 Hz), 4.35 (2H, q, J=7.1 Hz), 2.36 (3H, s), 2.33 (2H, d, J=4.7 Hz), 1.38 (3H, t, J=7.1 Hz), 1.33 (6H, s).
