Procedure
A mixture of [4-(4-iodobenzotriazol-1-yl)-pyrimidin-2-yl]-(1-methanesulfonyl-piperidin-4-yl)-amine (364 mg), 4-methyl-3-thiopheneboronic acid (109 mg) and Na2CO3 (2 M aq, 1.1 mL, degassed), toluene (13 mL, degassed) and EtOH (1 mL), was bubbled with argon and stirred at RT for 10 min in a screw cap pressure flask. To this was added Pd(PPh3)4 (25 mg), the flask sealed, and the mixture stirred overnight at 110° C. The reaction mixture was then cooled to RT, diluted in water, extracted in DCM, washed with water and brine, dried over Na2SO4, and the solvent stripped to yield a solid. The solid was chromatographed on silica, eluting with 0-30% Magic Base/DCM, then chromatographed again on silica using 0-100% EtOAc/hexanes. The product was titurated with Et2O, filtered, and evaporated in vacuo overnight to provide (1-methanesulfonyl-piperidin-4-yl)-{4-[4-(4-methyl-thiophen-3-yl)-benzotriazol-1-yl]-pyrimidin-2-yl}-amine (Compound 5, 219 mg). Mp=244.0-245.0° C.; M+H=470.
