Potassium Carbonate → (S)-tert-Butyl 4-(1-amino-3-(4-(2-methyl-1-oxoisoindolin-5-yl)phenyl)-1-oxopropan-2-ylcarbamoyl)tetrahydro-2H-pyran-4-ylcarbamate

Reaction Steps

Potassium carbonate (276 mg) in water (2.0 mL) was added to (S)-tert-butyl 4-(1-amino-3-(4-iodophenyl)-1-oxopropan-2-ylcarbamoyl)tetrahydro-2H-pyran-4-ylcarbamate (Example 1, step (iii), 517 mg), 2-methyl-1-oxoisoindolin-5-ylboronic acid (Example 31, step (iii), 191 mg) and 1,1 bis(di-tert-butylphosphino)ferrocene palladium dichloride (98 mg) in degassed acetonitrile (12 mL) at 20° C. under nitrogen. The resulting solution was stirred at 80° C. for 30 min. The reaction mixture was cooled, filtered and diluted with dichloromethane, and washed with water. The organic extract was dried over magnesium sulfate, filtered and evaporated to afford crude product. The crude product was purified by chromatography in silica eluting with methanol/ethyl acetate (5:95 to 15:85). Pure fractions were evaporated to dryness to afford the sub-titled compound (469 mg).
