Procedure

A degassed mixture of 2-chloro-4-morpholin-4-yl-6-(3-morpholin-4-yl-azetidin-1-ylmethyl)thieno[3,2-d]pyrimidine (400 mg, 0.98 mmol), 1,2-diaminobenzene (240 mg, 2.22 mmol), Pd(Oac)2 (64 mg, 0.29 mmol), rac-BINAP (88 mg, 0.14 mmol) and Cs2CO3 (480 mg, 1.47 mmol) in 1,4-dioxane (4 mL)) was subjected to microwave irradiation at 150° C. for 30 minutes. The reaction mixture was cooled to ambient temperature and loaded onto an Isolute® SCX-2 cartridge (25 g). The cartridge was then washed with MeOH and the desired product was subsequently eluted using 2 M NH3 in MeOH. The product was collected and concentrated in vacuo. The resultant residue was purified by flash chromatography (Si—PPC, DCM: 2 M NH3 in MeOH 100:0 to 98:2 to 96:4) to afford N-[4-morpholin-4-yl-6-(3-morpholin-4-yl-azetidin-1-ylmethyl)thieno[3,2-d]pyrimidin-2-yl]benzene-1,2-diamine as a pale yellow oil (310 mg, 66%). LCMS (Method C): RT=2.06 min, [M+H]− 482.4
