Reaction Steps

A glass microwave reaction vessel was charged with 2-fluoro-3-(tetrahydro-2H-pyran-4-yl)pyridine (0.3904 g, 2.154 mmol), 4-(benzo[d]thiazol-2-ylamino)phenol (0.783 g, 3.23 mmol), and cesium carbonate (2.106 g, 6.46 mmol) in N-Methyl-2-pyrrolidinone (7.18 mL). The reaction mixture was stirred and heated in a Biotage Initiator microwave reactor at 180° C. for 30 min. Reaction was worked up via seperatory funnel. The crude product was purified by reverse-phase preparative HPLC using a Phenomenex Synergi column, 4 micron, MAX-RP, 80 Å, 150×30 MM, 0.1% TFA in ACN/H2O, gradient 15% to 100% over 15 min. Further purification was pursued by absorbing crude product onto a plug of silica gel and chromatographed through a Biotage pre-packed silica gel column (25M), eluting with a gradient of 5% to 60% EtOAc in hexane, to provide N-(4-(3-(tetrahydro-2H-pyran-4-yl)pyridin-2-yloxy)phenyl)benzo[d]thiazol-2-amine. MS (ESI, pos. ion) m/z: 404.0 (M+1). IC50 (uM) +++++.
