Procedure

A glass microwave reaction vessel was charged with 2-fluoro-3-(tetrahydrofuran-3-yl)pyridine (1.00 g, 5.98 mmol), 4-(benzo[d]thiazol-2-ylamino)phenol (1.56 g, 6.44 mmol) and cesium carbonate (4.88 g, 14.98 mmol) in DMSO (10 mL). The reaction mixture was sealed under argon and was heated thermally at 100° C. for 24 h. The reaction was cooled to rt and diluted with water. The product turned into a gum and the aqueous solution was decanted. The gum was stirred over MeOH for 1 h resulting in a precipitate that was filtered, washed with MeOH and dried in vacuo to give the title compound as a white crystalline solid. MS (ESI, pos. ion) m/z: 389.9 (M+1). IC50 (uM) +++++.
