In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), a solution of commercially available 2,4-dibromo-thiazole (3.50 g, 14.41 mmol) in dry Et2O (120 ml.) was treated with n-BuLi (5.9 ml. of a 2.5M solution in hexanes, 14.72 mmol) at -78 0C. The reaction mixture was stirred at this temperature for 30 min. lambda/,lambda/-Dimethylformamide (1.35 ml_, 14.47 mmol) was then added and the mixture allowed to warm to rt over a period of 1 h. The reaction was quenched by the addition of sat. aq. NH4CI (50 ml_). The layers were separated and the aq. layer extracted with Et2O (3 x 50 ml_). The combined org. extracts dried over Na2SO4, filtered, and the solvents were removed under reduced pressure. Purification of the residue by FC (10:1 -> 3:1 hept-EA) gave the title compound as a pale yellow solid. TLC: rf (1 :1 hept-EA) = 0.21. LC-MS-conditions 02: tR = 0.81 min.

The organic layer was separated and concentrated to give 200 mg of 4-[(4-bromo-1,3-thiazol-2-yl)methyl]morpholine (76%).

YieldReaction ConditionsOperation in experiment
With sodium hydrogencarbonate; potassium carbonate; acetic acid; dimethyl amine; In 1,4-dioxane; water; 4-(dicyanomethylene)-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran; Example 355 5-{2-[(dimethylamino)methyl]-1,3-thiazol-4-yl}-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indole-7-carboxamide trifluoroacetate To a solution of <strong>[167366-05-4]4-bromo-1,3-thiazole-2-carbaldehyde</strong> (192 mg, 1.0 mmol) in DCM (4.0 mL) was added dimethyl amine (2.0M, 3.0 mL) and 3 drops of AcOH. The mixture was stirred for 48 hr and then Na(OAc)3BH (1.33 g, 6.0 mmol) was added. After 12 hr. the mixture was quenched with Sat. NaHCO3 (4.0 mL) and brine (3.0 mL) and separator was used to get the DCM organic layer. The organic layer was concentrated to give 90 mg of desired product (40%). To a solution of 3-[1-(ethylsulfonyl)-4-piperidinyl]-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indole-7-carboxamide (46 mg, 0.1 mmol), dimethylamine (69 mg, 0.3 mmol) and potassium carbonate (83 mg, 0.6 mmol) in dioxane (2 mL) and water (0.7 mL) was added triacetoxyborohydride (12 mg, 0.01 mmol). This mixture was degassed for 5 min. The mixture was then reacted in a microwave for 20 min at 160 C. The organic layers were separated and concentrated. It was then purified using Gilson Preparatory HPLC to afford 23 mg of the title compound (59%) LC/MS=m/z 474.4 [M+H] Ret. Time: 1.20
