Phosgene → 1-{[1-[1-(2-Hydroxy-indan-1-ylcarbamoyl)-2,2-dimethyl-propylcarbamoyl]-4-(7-methoxy-2-phenyl-quinolin-4-yloxy)-pyrrolidine-2-carbonyl]-amino}-2-vinyl-cyclopropanecarboxylic acid ethyl ester

Reaction Steps

To a solution of compound 12 (0.13 mmol) in THF (2 mL), was added a large excess of NaHCO3 (s) and a solution of phosgene in toluene (1.6 M, 600 μL). After 10 min of agitation the slurry was filtered and concentrated to dryness. The solid was redissolved in dichloromethane and a large excess of NaHCO3 (s) and 2-Amino-N-(2-hydroxy-indan-1-yl)-3,3-dimethyl-butyramide (0.65 mmol) was added. The slurry was agitated for 24-40 hrs at RT. The slurry was filtered, concentrated and subjected to silica column chromatography (gradient elution from 100% DCM to MeOH/DCM 2:98) to give the title compound (89.6 mg, 0.11 mmol). Purity by HPLC>95%. M+H+790.3.
