(2,4-Dichlorophenyl)methyl isocyanide (0.075 g, 0.4 mmol) and crude 2,2-dimethyl-4-oxobutanoic acid (0.115 g, 0.6 mmol) were dissolved in methanol (2 ml). Ethylamine solution (2M in water, 0.3 ml, 0.6 mmol) was added and the mixture was heated in a sealed vessel at 100° C. for 30 minutes in a microwave reactor. The mixture was left to stand over the weekend and then the solvent was removed in vacuo and the resulting orange oil was purified by mass-directed automated HPLC to give a clear oily gum which was triturated with diethyl ether to give N-[(2,4-dichlorophenyl)methyl]-1-ethyl-4,4-dimethyl-5-oxoprolinamide as a white solid (0.024 g). LC/MS [M+H]+=343, retention time=2.57 minutes.
