Conditions

Temperature
100 °C

Procedure

To a solution of (2,4-dichlorophenyl)methyl isocyanide (0.047 g, 0.25 mmol) and 4-oxobutanoic acid (15% in water, 0.26 ml, 0.4 mmol) in methanol (1.75 ml) was added cyclopropylamine (0.042 ml, 0.6 mmol). The mixture was heated to 100° C. for 30 minutes in a microwave reactor. The solvent was removed in vacuo and the residue was purified by mass-directed automated HPLC to give 1-Cyclopropyl-N-[(2,4-dichlorophenyl)methyl]-5-oxoprolinamide (0.072 g) as a white solid. LC/MS [M+H]+=326/328, retention time=2.29 minutes.
