Claim:
A method for preparing a pharmaceutical composition comprising the steps of (a) providing a compound of formula 1 wherein R 1 is hydrogen, —C 1-6 -alkyl, —C 1-6 -haloalkyl, —OH, —O—C 1-6 -alkyl, halogen, aryl, or a heterocycle, wherein R 1 may be substituted by 1, 2, 3, 4, or 5 identical or different groups R 5 ; R 5 is halogen, —CN, —NO 2 , —C 1-6 -alkyl, —C 3-6 -cycloalkyl, —C 1-6 -haloalkyl, —CO—R 6 , —COO—R 6 , —CON—R 6− R 7 , —O—R 6 , —N—R 6— R 7 , —N—R 6− CO—R 7 , —N—R 6 —SO 2 —R 7 , —S—R 6 , —SO—R 6 , —SO 2 —R 6 or —SO 2 N—R 6 —R 7 , —C 2-6 -alkylene, —C 2-6 -alkenylene, or —O—C 1-6 -alkylene-O—; wherein R 6 and R 7 are individually hydrogen, —C 1-6 -alkyl, or —C 3-6 -cycloalkyl; R 2 is hydrogen, —C 1-6 -alkyl, -or C 1-6 -haloalkyl; R 3 is —C 1-6 -alkyl; R 4 is —OH, —NH 2 , or halogen; and n is 0, 1, 2, or 3; or an isomer, enantiomer, or racemate thereof, in the form of a free base or an acid addition salt, and (b) combining said compound of the formula I with at least one excipient or additive to obtain the pharmaceutical composition.
