Generate synthesis code of a compound that describes the total synthesis in a short text line using the identifiers of the reaction and the reactants. The synthesis code will be added to the output file. 
<Field name in scheme>(<Field name in reactant 1>, <Field name in reactant 2>):<Product list index>/<Product index>.

For example: Friedel-Crafts acylation(AromaticID038, AcidHalideID038):1/1
