To a solution of 2-chloro-5,7-dihydro-4-((S)-3-methylmorpholino)thieno[3,4-d]pyrimidine (100 mg, 0.37 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 (124 mg, 0.41 mmol), and Na2CO3 (118 mg, 1.11 mmol) followed by addition of PdCl2(dppf) (15 mg, 0.02 mmol). The resulting mixture was heated to 70° C. and stirred overnight under nitrogen. The solvent was removed under reduced pressure to give a residue which was partitioned between ethyl acetate and water. The organic layer was washed with brine dried (Na2SO4) and concentrated to give a crude product which was purified by preparative TLC (DCM/MeOH=20/1) to give the desired product, as a yellow solid (20 mg, 13%).
