3
alkyl;
R4 and R5 represent hydrogen; or
R4 represents hydrogen, R5 represents methyl; or
R4 represents methyl, R5 represents CH
2
R6 group in which R6 is C
1
-C
3
alkoxycarbonyl, carboxyl, hydroxyl group optionally substituted with methyl or benzyl; or
R4 and R5 together with the carbon atom they are attached to form 5- or 6-membered saturated heterocycle including at least one oxygen atom or nitrogen atom optionally substituted with methyl.
