Compounds of formula (IA) and their pharmaceutically acceptable salts are described. Processes for their preparation, pharmaceutical compositions containing them, their use as medicaments and their use in the treatment of bacterial infections are also described.
The present invention provides a compound useful as a synthetic intermediate for an anti-HIV agent having an integrase inhibitory activity, a production method thereof, and a production method of an anti-HIV agent using the synthetic intermediate. Specifically, the present invention provides, for example, compounds represented by the formulas (6), (7-1), (7-2) and (8):
wherein R is a fluorine atom or a methoxy group, R
1
is a C
1
-C
4
alkyl group, R
2
is a hydroxyl-protecting group, and X
2
is a halogen atom, a production method thereof, and a production method of an anti-HIV agent using the synthetic intermediate.
