実験手順
Methyl 2-(4-(3-(cyclohexylmethyl)-2-oxo-2,3-dihydro-1H-imidazo[4,5-b]pyrazin-5-yl)phenyl)acetate. Bromo-1-(cyclohexylmethyl)-4-imidazolino[4,5-b]pyrazin-2-one (200 mg, 0.64 mmol), methyl 2-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]acetate (213 mg, 0.77 mmol), dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium (II) dichloromethane (53 mg, 0.06 mmol) and potassium phosphate (543 mg, 2.56 mmol) in DMF (20 mL) and water (5 mL) were reacted according to General Procedure B. The product was purified by reverse-phase semi-preparatory HPLC (30-100% acetonitrile+0.1% TFA in H2O+0.1% TFA, over 30 min). The desired fractions were concentrated, and the residue was taken up in DMSO (2 mL) and heated at 100° C. until completely dissolved. Water was added upon cooling and the desired product precipitated out of solution. The precipitate was collected by vacuum filtration, washed with water and dried under high vacuum to provide the title compound (95 mg, 39 yield) as a tan solid. MS (ESI) m/z 381.4 [M+1]+.
