Commercially available Pd/C can be used as a catalyst for nitro group reductions with only 0.4 mol % Pd loading. The reaction can be performed using either silane as a transfer hydrogenating agent or simply a hydrogen balloon (μ1 atm pressure). With this technology, a series of nitro compounds was reduced to the desired amines in high chemical yields. Both the catalyst and surfactant were recycled several times without loss of reactivity.

Benzimidazolinone derivatives of the general formula (I): STR1 wherein R1, R2 and R3, which may be the same or different, each is a hydrogen or halogen atom or a lower alkyl, halo-lower alkyl, hydroxy-lower alkyl, hydroxyl, lower alkoxy, aryloxy, acyl, cyano, carboxyl, a lower alkoxycarbonyl, carbamoyl, nitro or nitrogen-containing 5- or 6-membered heterocyclic group; A is an ethylene group which may optionally have at least one branch; R4 and R5, which may be the same or different, each is a lower alkyl group or R4 and R5, together with the adjacent nitrogen atom, represent a pyrrolidinyl, piperidino or a morpholino group provided that when STR2 is a piperidino or diethylamino group, at least one of R1, R2 and R3 is other than a hydrogen atom, or pharmaceutically acceptable salts thereof, methods of producing the same and pharmaceutical compositions containing the same are disclosed. Pharmacologically, the above compounds (I) have pulmonary surfactant secretion promoting activity.
