Procedure

Into a round bottom flask, under an atmosphere of nitrogen, [1,1′-bis(diphenyl phosphino) ferrocene]dichloro palladium (II), complex with dichloromethane (1:1), was placed with toluene (15 mL, 140 mmol). [4-Chloro-5-(1H-pyrrolo[2,3-b]pyridin-3-ylmethyl)-thiazol-2-yl]-(4-fluoro-benzyl)-amine (P-0156,145 mg, 0.4 mmol) was added in 5 ml of toluene at room temperature. The mixture was stirred for 10 minutes. To the stirring reaction, a solution of 3.13 Methyl magnesium bromide in ether (1.86 mL) was added dropwise at room temperature. The opaque solution was heated to 60° C. Tetrahydrofuran (10 mL) was added to the warm solution. The mixture was heated to reflux for an additional two hours. After cooling to 0° C., the reaction was quenched with a solution of citric acid at pH 4-5 in ice-water and stirred to room temperature. The mixture was diluted with ethyl acetate and washed with saturated sodium bicarbonate and brine. The organic layer was dried over anhydrous sodium sulfate and the solvent was removed under reduced pressure. Purification with flash chromatography, eluting with a gradient of ethyl acetate:hexanes (20:100), gave a yellow solid that was further washed with ethyl acetate to give P-0162 (15 mg, 10%) as an off-white solid. MS (ESI) [M+H+]+=367.2.
