Patent ID: 8394823

Claim:
A compound according to Formula (I): or stereoisomers or salts thereof, wherein: A is alkyl, cycloalkyl, heterocyclyl, aryl, —C(O)R 4 , —C(O)OR 4 , or —C(O)NR 4 R 5 ; R 1 and R 2 are independently hydrogen, alkyl, —(CH 2 ) n -(cycloalkyl), —(CH 2 ) n -(aryl), —(CH 2 ) n -(heterocyclyl), aryl, and/or heterocyclyl, or R 1 and R 2 together with the carbon atom to which they are attached, form a 3- to 7-membered cycloalkyl or 4- to 7-membered heterocyclyl ring with one or two heteroatoms; n is an integer in the range of zero to 4; R 3 is hydrogen or alkyl; R 4 is alkyl, cycloalkyl, heterocyclyl, or aryl; and R 5 is hydrogen or alkyl, or R 4 and R 5 together with the nitrogen atom to which they are attached, form a 4- to 7-membered heterocyclyl ring with one or two heteroatoms; wherein: each of said alkyl is substituted with 0-3 R a ; each of said cycloalkyl is substituted with 0-3 R a ; each of said heterocyclyl is substituted with 0-4 R b ; and each of said aryl is substituted with 0-4 R b ; R a is, independently at each occurrence, F, Cl, Br, —CF 3 , —OH, —CN, —NR c R d , and/or C 1 -C 3 alkoxy; R b is, independently at each occurrence, C 1 -C 4 alkyl, F, Cl, Br, —CF 3 , —OH, —CN, —NR c R d , and/or C 1 -C 3 alkoxy; and R c and R d are, independently at each occurrence, H and/or C 1 -C 4 alkyl, or R c and R d together with the nitrogen atom to which they are attached, form a 4- to 7-membered heterocyclyl ring with one or two heteroatoms.
