Question

What is/are the limiting reagent(s) for this three-step procedure?  Why is sodium borohydride not the limiting reagent even though a smaller number of moles of this reagent are used?

Mass/volume used in experiment:

O-vanillin = 0.760g

P-toluidine = 0.535g

Ethanol = 15 ml

Sodium borohydride = 0.1 g

Glacial acetic acid = 2 ml

Acetic anhydride = 2 ml
