"USE OF 2,4-BIS (ALKYLAMINE) PYRIMIDINES OR -KINAZOLINES REPLACED AS ANTIMICROBIANS". The use of 2,4-bis (alkylamino) pyrimidines of formula R 1 is C 1 -C 12 alkyl or C 6 -C 10 aryl; R 2 is hydrogen or C 1 -C 12 alkyl; or R 1 and R 2 together form a radical of the formula, wherein R <39> and R <39> <39> are each independently of the other hydrogen, C 1 -C 6 alkyl, or C 1 -C 6 alkoxy; R 3 and R 5 are each independently of the other hydrogen or C 1 -C 8 alkyl; R 4 is C 1 -C 2 alkyl, unsubstituted phenyl, C 6 C 10 aryl, C 6 C 10 aryl C 1 C ~ 6-alkyl, C 1-1 hydroxy-C 1-6 alkyl, di-C 1-6 -C 1-6 alkylamino-C 1-6 alkylamino, mono-C 1-1 alkyl C6-6 alkylamino-C6-6 alkylamino, - (CH2-2) -2- (O- (CH2-2) -2-) -1-4 -OH or - (CH ~ 2 ~) ~ 2 ~ - (O- (CH ~ 2 ~) ~ 2 ~) ~ 1-4 ~ -NH ~ 2 ~; R ~ 6 ~ is C ~ 1 ~ -C ~ 20 ~ alkyl, C ~ 6 ~ -C ~ 10 ~ aryl, C ~ 6 ~ -C ~ 10 ~ aryl-C ~ 1 ~ -C ~ 8 ~ alkyl, hydroxy -C ~ 1 ~ -C ~ 6-alkyl, di-C ~ 1 ~ -C ~ 6-C-alkylamino-C ~ 1 ~ -C ~ 6-alkyl, mono-C-1 ~ -C ~ 6-alkylamino-C ~ 1 ~ -C ~ 6 ~ alkyl, - (CH ~ 2 ~) ~ 2 ~ - (O- (CH ~ 2 ~) ~ 2 ~) ~ 1-4 ~ -OH or - (CH ~ 2 ~) ~ 2 ~ - (O- (CH ~ 2 ~) ~ 2 ~) ~ 1-4 ~ -NH ~ 2 ~; or R3 and R4 and / or R5 and R6 together form a pyrrolidine, piperidine, hexamethyleneimine or morpholine ring; in antimicrobial surface treatment. |
