To a stirred solution of (S)-1-cyclopropyl-3-(4-(4-(3-methylmorpholino)-6,7-dihydro-5H-pyrrolo[3,4-d]pyrimidin-2-yl)phenyl)urea (example 3) (150 mg, 0.38 mmol) in 2-methyl THF (2 mL) and DMSO (1 mL) was added DIPEA (159 uL, 0.92 mmol), cyclopropane carboxylic acid (578 uL, 0.73 mmol) and EDC (139 mg, 0.73 mmol), followed by HOBt (98 mg, 0.73 mmol). The reaction mixture was stirred at room temperature for 4 h then diluted with water and ethyl acetate. The organic layer was concentrated and purified by prep HPLC (low pH) to give a pale yellow solid (65 mg, 0.14 mmol, 37% yield).
