Patent ID: 6995167

Claim:
A compound of formula I, wherein NRR 1 is attached at the 5- or 6-position of the furopyridine ring; R is hydrogen, C 1 –C 4 alkyl, or COR 2 ; R 1 is —CH 2 CH═CHAr n is 0 to 3; A is N; Ar is a 5- or 6-membered aromatic or heteroaromatic ring which contains zero to four nitrogen atoms, zero to one oxygen atoms, and zero to one sulfur atoms which aromatic or heteroaromatic ring is optionally substituted with one to two substituents independently selected from: halogen, trifluoromethyl, or C 1 –C 4 alkyl; R 2 is hydrogen, C 1 –C 4 alkyl; C 1 –C 4 alkoxy; or a phenyl ring optionally substituted with one to three of the following substituents: halogen, C 1 –C 4 alkyl, C 2 –C 4 alkenyl, C 2 –C 4 alkynyl, OH, —OC 1 –C 4 alkyl, —CO 2 R 5 , —CN, —NO 2 , —NR 3 R 4 , or —CF 3 ; R 3 , R 4 and R 5 are independently hydrogen; C 1 –C 4 alkyl; or a phenyl ring optionally substituted with one to three of the following substituent: halogen, C 1 –C 4 alkyl, C 2 –C 4 alkenyl, C 2 –C 4 alkynyl, —OH, —OC 1 –C 4 alkyl, —CN, —NO 2 , or —CF 3 ; or an enantiomer thereof, or a pharmaceutically acceptable salt thereof.
