Procedure

Part A: A mixture of ethyl 1-(4-chlorophenyl)-2-(2,4-dichlorophenyl)-4,5-dihydro-1H-imidazole-4-carboxylate (3.97 g, 0.01 mol) in methanol/water is reacted with LiOH (1.3 gram, 0.054 mol) at room temperature for 16 hours. The resulting mixture is concentrated in vacuo to give crude lithium 1-(4-chlorophenyl)-2-(2,4-dichlorophenyl)-4,5-dihydro-1H-imidazole-4-carboxylate (4.7 gram).
