Step1. This is a grignard reaction aldehyde on reaction with phenyl magnesium bromide we will get secondary alcohol as a product.
Step2. This is oxidation of secondary alcohol by using chromic acid so we will get ethyl phenyl ketone as a product.
Step3. Reaction of keton and amine in presence of acid we will get imine as a product.
