3-(1-aminoethyl)-4-phenyl-1H-isochromen-1-one hydrochloride (intermediate E2, 50 mg, 0.166 mmol), 4-chlorothieno[3,2-d]pyrimidine (36.8 mg, 0.215 mmol), triethylamine (0.046 ml, 0.331 mmol) were reacted in 2-methylpropan-2-ol (1 ml) at 50° C. for 24 hrs and at 80° C. for 27 hrs. 4-Chlorothieno[2,3-d]pyrimidine (5.7 mg, 0.033 mmol), triethylamine (0.09 ml, 0.066 mmol) were added and the mixture reacted at 90° C. for 4 hrs. The crude was purified via reverse phase chromatography with a Biotage C18 30 g SNAP column (Phase A, water 95%, ACN 5%, formic acid 0.1%); Phase B ACN 95%, water 5%, formic acid 0.1%) to give the title compound (33 mg, 50%).
