Reaction Steps
(R)-5-(4-Cyano-benzyl)-7-(3,5-dichloro-4-fluoro-phenyl)-5-methyl-6-oxo-6,7-dihydro-5H-imidazo[1,2-a]imidazole-3-carboxylic acid (44 g, 95.8 mmol) was dissolved in CH2Cl2 (600 mL). To this solution was added oxalyl chloride (16.7 g) followed by DMF (0.3 mL). After 2 h, the volatiles were removed and the resultant residue was placed under high vacuum for 18 h to yield the title compound. The title compound was used without purification.
