Procedure

To a solution of 2-chloro-7,8-dihydro-4-((S)-3-methylmorpholino)-6H-thiopyrano[3,2-d]pyrimidine (150 mg, 0.53 mmol) in DME/H2O (4:1, 10 mL) was added 1-cyclopropyl-3-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)urea (175 mg, 0.58 mmol) and Na2CO3 (170 mg, 1.60 mmol) followed by PdCl2(dppf) (15 mg, 0.02 mmol). The resulting mixture was stirred overnight at 70° C. under nitrogen. The solvent was removed under vacuum to give a residue which was partitioned between ethyl acetate and water. The organic layer was separated and dried over anhydrous Na2SO4. The solvent was removed to give crude material which was purified by preparative TLC (DCM/MeOH=20/1) to give the desired productas a white solid (180 mg, 80%).
