Example of a dehydration reaction
Web2-Pentylcinnamaldehyde, commonly called flosal, is a perfume ingredient with a jasmine-like odor. Flosal is an α,β-unsaturated aldehyde made by a crossed aldol reaction between benzaldehyde (C6H5CHO) and heptanal (CH3CH2CH2CH2CH2CH2CHO), followed by dehydration. Draw a stepwise mechanism for the following reaction that prepares flosal.
