Reaction Steps

Methanesulfonic acid 2-(4-{2-[2-(3,5-difluoro-phenyl)-acetylamino]-pentanoylamino}-imidazol-1-yl)-ethyl ester (1 equiv) was dissolved in acetonitrile and treated with potassium carbonate (1.5 equic) and morpholine (3 equiv). The reaction was heated to 65° C. for 18 h and quenched with water, extracted with methylene chloride, dried, and concentrated. The residue was purified by column chromatography to afford the title compound: C13 NMR (100 MHz, CDCl3) 14.0, 18.9, 36.0, 43.1, 45.1, 53.1, 53.9, 58.9, 67.1, 102.6, 102.9, 107.9, 112.3, 112.6, 133.5, 137.6, 139.0, 161.0, 162.0, 169.3, 169.4; MS m/z 450.1 (M+1).
