Procedure
Treat a suspension of 5-(4-bromo-3-methoxy-phenyl)-2-(4-chloro-phenyl)-6,7-dihydro-5H-thiazolo[5,4-c]pyridin-4-one (0.25 mg, 0.56 mmol), 1-prop-2-ynyl-pyrrolidine (0.12 g, 1.10 mmol), dichlorobis(triphenylphosphine)palladium (II) (12.0 mg, 0.02 mmol), triethylamine (0.5 mL) in DMF with CuI (4.0 mg, 0.02 mmol). Stir at 80° C. under nitrogen for 2 days. Dilute the reaction with water and extract with CH2Cl2 (2×). Dry, filter, and concentrate the organic solution and purify the crude material by flash chromatography, using a gradient of 0-10% MeOH in CH2Cl2 to give the title compound (30.0 mg, 12%). MS (ES+) 478.0 (M+1)+. 1H NMR (400 MHz, CDCl3): δ 7.89 (d, 2H, J=8.8 Hz), 7.40 (m, 3H), 6.95 (d, 1H, J=2.2 Hz), 6.82 (dd, 1H, J=8.1, 2.0 Hz), 4.10 (t, 2H, J=6.8 Hz), 3.84 (m, 5H), 3.26 (t, 2H, J=6.8 Hz), 2.88 (m, 4H), 1.89 (m, 4H).
