Preparation of Lacidipine:
Firstly, o-benzenedimethanal is mixed with triphenyl phosphine acetic acid tert-butyl to generate 3-(2-formyl-phenyl) acrylic acid tert-butyl. The reaction needs solvent dichloromethane at 0 °C for 15 minutes. Then 3-(2-formyl-phenyl) acrylic acid tert-butyl reacts with 2-amino-2-butene ethyl and solvent acetic acid for 5 hours at room temperature to obtain product.
Lacidipine is prepared by reaction of o-benzenedimethanal, triphenyl phosphine acetic acid tert-butyl and 2-amino-2-butene ethyl.
