Procedure

To scintillation vial with a magnetic stir-bar was added 7-(3-amino-propenyl)-2-(4-fluoro-2-methyl-phenylamino)-1,6-dimethyl-1,8-dihydro-imidazo[4,5-h]isoquinolin-9-one (68 mg, 173 mmol), followed by dimethylformamide (DMF) (1.0 mL) and triethylamine (TEA) (0.25 mL). To a separate scintillation vial was added 1-methyl-1-oxo-1λ5-phosphinane-4-carboxylic acid (130 mg, 0.74 mmol, mixture of cis/trans isomers), HATU (300 mg, 0.79 mmol), and DMF (2.0 mL), followed by TEA (0.25 mL). The solution was sonicated until most of the solids were dissolved. A solution of the activated ester (1.0 mL, or roughly half) was transferred to the solution of amine and stirred for 2.5 hours at room temperature, after which time the starting material was completely consumed as determined by LC-MS. The reaction mixture was quenched by addition of water (0.5 mL), then acidified with TFA. The mixture was filtered (syringe membrane filter) and purified directly by reverse-phase HPLC to provide 2-(4-fluoro-2-methyl-phenylamino)-1,6-dimethyl-7-{3-[(1-methyl-1-oxo-phosphinan-4-yl)carbonylamino]-propenyl}-1,8-dihydro-imidazo[4,5-h]isoquinolin-9-one (24.9 mg, 26%) as a mixture of cis/trans isomers. 1H NMR (400 MHz, d6-DMSO) δ 11.12 (s, 1H), 10.55 (s, 1H), 8.21-8.17 (m, 1H), 7.74 (d, J=8.6Hz, 1H), 7.69 (d, J=8.6Hz, 1H), 7.55 (dd, J1=5.9 Hz, J2=9.0 Hz, 1H), 7.27 (td, J1=2.7 Hz, J2=8.6 Hz, 1H), 6.66 (d, J=15 Hz, 1H), 6.55-6.49 (m, 1H), 4.18 (s, 3H), 3.92 (m, 2H), 2.31 (s, 3H), 2.30 (s, 3H), 2.35-2.30 (m, 1H), 2.08-1.90 (m, 6H), 1.78-1.65 (m, 2H), 1.52-1.47 (m, 3H); ESMS m/z: found, 550 (M+1)+.
