Reaction Steps
Into a vial was added the [B] 4-bromo-2-fluoro-N-thiazol-2-yl-benzenesulfonamide (170 mg, 0.00050 mol), sodium tert-butoxide (117 mg, 0.00121 mol), 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene (18 mg, 0.000030 mol), Tris(dibenzylideneacetone)dipalladium(0) (9.3 mg, 0.000010 mol) and 1,4-dioxane (1.58 mL, 0.0202 mol). Argon was bubbled for 15 minutes. Into the reaction was added the [2,4-dimethoxy-benzyl)-methyl-amine (110 mg, 0.00061 mol) and the reaction mixture was heated at 100° C. overnight. The reaction mixture was cooled to room temperature then filtered over Celite. The filtrate was concentrated to give the crude compound as a yellow solid that was used in the next step without purification.
