Metabolism studies with ethyl [5-amino-1,2-dihydro-2-methyl-3- phenylpyrido[3,4-b]pyrazin-7-yl]carbamate (1) in mice were reported previously to give a hydroxylated metabolite, which was methylated to give a methoxy derivative. The metabolite and its deri

Reactive aromatic compounds are acylated without racemisation to aryl 1-phthalimidoalkyl ketones 4 in good yields with N-phthaloyl-α-amino acid chlorides in the presence of catalytic amounts (1 to 5 mol-percent) of FeCl3.This new method is especially useful for the synthesis of the pharmacologically interesting alkoxyaryl 1-phthalimidoalkyl ketones 6, 8, 10, and 11, which cannot be prepared in reasonable yields in the presence of other FC catalysts such as AlCl3 or SnCl4.
