72 mg dibenzyl {[(3,5-dichloro-phenylsulphonyl)-naphthalen-2-yl-amino]-methyl}-phosphonate in 6 ml of methanol are hydrogenated in the presence of 3 mg palladium on activated charcoal (10% Pd). The catalyst is filtered through kieselguhr and the filtrate is evaporated down in vacuo. The flask residue is stirred with diisopropylether, suction filtered and dried.
