Reaction Steps

To a solution of 4-(benzo[d]thiazol-2-ylamino)phenol (0.094 g, 0.390 mmol) and methyl 4-(3-chloropyrazin-2-yl)tetrahydro-2H-pyran-4-carboxylate (0.1 g, 0.390 mmol) in DMSO (1 mL) was added cesium carbonate (0.254 g, 0.779 mmol). The resulting mixture was heated to 163° C. for ˜20 minutes. Reaction mixture was cooled back to 100 C and stirred overnight. Aqueous work up with multiple water and brine washes to remove DMSO and extraction with DCM. Purification by Shimadzu (phenomenex Gemini C18 5 um 100×30 mm; 254 UV; solvent A=0.1% TFA in water, solvent B=0.1% TFA in ACN; gradient run: 35% B to 80% B in 9 min; 1 min@ 80% B; flow rate=30 ml/min; 2 peaks contained mass 418: R1=3.91 to 4.26 min; R2=5.83 to 6.36 min) to afford the product. MS (ESI, pos. ion) m/z: 419.0 (M+1). IC50 (uM) +++++.
