실험 절차

To a solution of 1-(((5S,7S)-3-(5-(2-(2-hydroxyethoxy)propan-2-yl)pyrazin-2-yl)-7-methyl-2-oxo-1-oxa-3-azaspiro[4.5]decan-7-yl)methyl)-1H-benzo[d]imidazole-6-carbonitrile (60 mg, 0.119 mmol) in dichloromethane (DCM) (1127 μl) was added DIEA (62.3 μl, 0.357 mmol) and dimethylphosphinic chloride (40.1 mg, 0.357 mmol) at RT. The mixture was stirred for 2 hours, concentrated and reconstituted in DMSO/MeOH and filtered. The solution was purified by reverse phase HPLC (Waters Sunfire 30×150 mm Acetonitrile: Water TFA 30-70%, 50 mL/min, 15 min.). The product was free based with PL-HCO3 resin SPE to yield 2-((2-(5-((5S,7S)-7-((6-cyano-1H-benzo[d]imidazol-1-yl)methyl)-7-methyl-2-oxo-1-oxa-3-azaspiro[4.5]decan-3-yl)pyrazin-2-yl)propan-2-yl)oxy)ethyl dimethylphosphinate as a white solid (5.8 mg, 8%). 1H NMR (400 MHz, DMSO-d6) δ 9.24 (d, J=1.51 Hz, 1H), 8.60 (d, J=1.26 Hz, 1H), 8.48 (s, 1H), 8.38 (s, 1H), 7.83 (d, J=8.53 Hz, 1H), 4.12-4.21 (m, 2H), 3.94-4.03 (m, 2H), 3.88 (dd, J=23.09, 10.04 Hz, 2H), 3.42 (t, J=4.77 Hz, 2H), 2.00 (d, J=13.30 Hz, 1H), 1.88 (d, J=14.05 Hz, 1H), 1.59-1.78 (m, 3H), 1.30-1.56 (m, 15H), 1.07 (s, 3H). MS (m/z) 581.3 (M+H+).
