Patent ID: 7812167

Claim:
A compound of the formula R—NH-Q (I) wherein (i) Q is a radical in which R 3 is an alkoxy; Y is nitrogen; and R is a radical of the formula wherein R 4 is C 2-4 alkyl, C 3-7 cycloalkyl or C 5-7 heterocycloalkyl; R 5 and R 6 are independently hydrogen, halogen, cyano, R 7 , —C(O)R 7 or —S(O) 2 R 7 wherein R 7 is —(CR 8 R 9 ) m —W—R 10 in which R 8 and R 9 are independently hydrogen or lower alkyl; W is a bond, R 10 is hydrogen, alkyl, cycloalkyl, aryl or heterocyclyl; m is zero or an integer from 1 to 5; and n is zero or an integer of 1 or 2; or an optical isomer thereof; or a pharmaceutically acceptable salt thereof; or (ii) Q is a radical in which R 3 is alkoxy; and R is a radical of the formula wherein R 4 is C 2-4 alkyl, C 3-7 cycloalkyl or C 5-7 heterocycloalkyl; R 5 and R 6 are independently hydrogen, halogen, cyano, R 7 , —C(O)R 7 or —S(O) 2 R 7 wherein R 7 is —(CR 8 R 9 ) m —W—R 10 in which R 8 and R 9 are independently hydrogen or lower alkyl; W is a bond; R 10 is hydrogen, alkyl, cycloalkyl, aryl or heterocyclyl; m is zero or an integer from 1 to 5; and n is zero or an integer of 1 or 2; or an optical isomer thereof; or a pharmaceutically acceptable salt thereof.
