Patent ID: 7105523

Claim:
A compound of the formula (I) in which R 1 is hydrogen or a di-C 1-6 -alkylaminocarbonyl radical, R 2 is a radical of the formula —O—CX—NR 3 R 4 , where X is O or S; R 3 and R 4 may be identical or different from one another and each is a radical chosen from H, optionally substituted C 1-6 -alkyl, optionally substituted C 1-6 -alkoxy-C 1-6 -alkyl, optionally substituted hydroxy-C 1-6 -alkyl, optionally substituted C 2-6 -alkenyl, optionally substituted C 1-6 -alkylcarbonyloxy-C 1-6 -alkyl, optionally substituted C 1-6 -alkoxycarbonyl-C 1-6 -alkyl, optionally substituted hydroxycarbonyl-C 1-6 -alkyl, phenyl which is optionally substituted by a C 1-6 -alkyl radical, a saturated five- to seven-membered heterocycle which is optionally linked via a C 1-6 -alkyl radical to the nitrogen atom, and optionally substituted C 3-8 -cycloalkyl, where R 3 and R 4 cannot simultaneously be H; or R 3 and R 4 together with the nitrogen atom to which they are bonded form a five- to seven-membered saturated heterocycle which may optionally contain a further heteroatom chosen from N, O, and S and/or may optionally be substituted or fused to a phenyl ring; or a salt, stereoisomer, tautomer, or hydrate thereof.
