Claim:
A compound of the formula (I) in which R 1 is NH 2 or is NHCO—C 1-6 -alkyl; R 2 is a radical of the formula R 3 NCOR 4 which is bonded via the nitrogen atom to the remainder of the molecule, where R 3 and R 4 together with the amide group to which they are bonded form a five- to seven-membered heterocycle which may be saturated or partially unsaturated, may optionally contain a further heteroatom chosen from N, O, and S, and may have 1 to 5 further substituents chosen from oxo, C 1-6 -alkyl, hydroxyl, hydroxy-C 1-6 -alkyl, and halogen, and may be fused to a C 6-10 -aryl ring or to a C 3-8 -cycloalkyl ring in which two carbon atoms are optionally connected together via an oxygen atom; or a salt, stereoisomer, tautomer, or hydrate thereof.
