Procedure vs. synthetic method?
Procedure/flow chart is a short, often diagrammatic, summary of a reaction sequence with reagents, solvents, temperature &amp; yields. It is expected that a competent synthetic chemist would be familiar with the reactions shown and would be able to understand how the product was made.

Synthetic method contains all the details of the reaction. Sources and quantities of reagents and solvents, times and temperatures of reaction, workup and purification procedures, characterisation of product.
