Procedure

To a stirred solution of (S)-1-[(R)-5-(4-cyano-benzyl)-7-(3,5-dichloro-phenyl)-5-methyl-6-oxo-6,7-dihydro-5H-imidazo[1,2-a]imidazole-3-sulfonyl]-pyrrolidine-2-carboxylic acid (see Example 5) (82 mg, 0.14 mmol) in anhydrous methylene chloride (1 mL) and HATU (82 mg, 0.21 mmol) was added DIPEA (73 μL, 0.42 mmol) and the mixture was stirred for 10 min at room temperature under nitrogen. (S)-1-Amino-propan-2-ol (0.21 mmol) was added and the mixture was stirred for 2 h at room temperature under nitrogen. The material was purified by column chromatography over silica gel to provide 62 mg of the title compound as a white solid (M+1, 631.2).
