The present disclosure provides a method for multicomponent one-pot synthesis of an intermediate of atorvastatin calcium. In particular, the present disclosure provides a method for multicomponent one-pot synthesis of 4-(4-fluorophenyl)-2-(2-methylpropionyl)-3-phenyl-4-oxoN-phenylbutanamide, characterized in that the target compound is synthesized by reacting N-phenylphenylpropynamide with 4-fluorobenzaldehyde and isobutyraldehyde under the action of a catalyst of Cu(SbF6)2 and a Pd-ligand by a one-pot process. This one-pot process is in line with the characteristics of green chemistry and high-atom economy, significantly reduces the emissions of the three-waste and pollution factors, and has fewer reaction steps and a yield (about 80% to 87%) significantly higher than the yield of the existing multi-step synthesis technical solutions. It uses easily available raw materials, has simple process operations, a low risk in EHS, and high industrial practicability.
