実験手順

To a solution of (S)-1-cyclopropyl-3-(4-(4-(3-methylmorpholino)-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidin-2-yl)phenyl)urea (example 15) (102 mg, 0.25 mmol) in DCM (3 mL) at room temperature (20° C.) was added ethyl isocyanate (32 uL, 0.27 mmol). The reaction mixture was stirred for 5 h. The solvent was removed in vacuo and the residue purified by prep HPLC (low pH) to afford an orange solid (40 mg, 33%).
