Patent ID: 8314089

Claim:
A method for treating retroviral diseases in humans and animals by administering a compound of formula in which R 1 represents phenyl, whereby phenyl is substituted with 1 to 3 substituents, whereby the substituents are selected independently of one another from the group consisting of halogen, cyano, nitro, trifluoromethyl, trifluoromethoxy, trifluoromethylthio, (C 1 -C 4 )-alkyl and (C 1 -C 4 )-alkoxy, R 2 represents phenyl, whereby phenyl may be substituted with 1 to 3 substituents, whereby the substituents are selected independently of one another from the group consisting of halogen, cyano, nitro, trifluoromethyl, trifluoromethoxy, trifluoromethylthio, C 1 -C 4 alkyl and C 1 -C 4 alkoxy, R 3 represents a 5- to 8-membered heterocycle bonded via nitrogen, whereby the heterocycle may be substituted with 1 to 3 substituents, whereby the substituents are selected independently of one another from the group consisting of halogen, hydroxy, hydroxymethyl, formyl, amino, oxo, trifluoromethyl, trifluoromethoxy, (C 1 -C 4 )-alkyl, (C 1 -C 4 )-alkoxy and (C 1 -C 4 )-alkoxycarbonyl, or one of its salts, to a human or animal in need thereof.
