Our attention has been drawn to the elegant work of Kaupp, Pogodda and Schmeyers entitled 'Gas/Solid Reactions with Acetone' (Chem. Ber., 1994, 127, 2249-2261) who use a somewhat different strategy for making the salt of benzodiazepine via a gas phase reactor with acetone. Our paper complements this work and provides an alternative route to the product, which may well be optimised in the future to give similar yields.
