HCID 78373Dimethylformamide dimethyl acetalSolvent

Procedure

1 mmol of tert-butyl 4-[2-(2,4-dichlorophenyl)-2-oxoethyl]piperazinecarboxylate was heated to 80° C. in neat N,N-dimethylformamidedimethyl acetal for six hours. The reaction mixture was concentrated in vacuo and purified by trituration with diethyl ether to obtain tert-butyl 4-{2-(2,4-dichlorophenyl)-1-[(dimethylamino)methylene]-2-oxoethyl}piperazinecarboxylate.
