Reaction Steps
BOP coupling of (S)-3-Cyclohexyl-2-(1-oxo-1,3-dihydro-isoindol-2-yl)-propionic acid (prepared in Example 1, Step A; 287 mg; 1.00 mmol) and 2-aminoimidazole (241 mg; 1.79 mmol) in a manner similar to that used for the preparation of (S)-3-cyclohexyl-2-(1-oxo-1,3-dihydro-isoindol-2-yl)-N-thiazol-2-yl-propionamide (outlined in Example 1, Step B) provided after flash chromatography (Biotage 40M; eluent: 4% methanol/methylene chloride) 320 mg of (S)-3-Cyclohexyl-N-(1H-imidazol-2-yl)-2-(1-oxo-1,3-dihydro-isoindol-2-yl) propionamide which was then recrystallized from ethyl acetate/hexanes to give 209 mg of pure material: EI-HRMS m/e calcd for C20H24N4O2 (M+) 352.1899, found 352.1895.
