Abstract

The invention relates to a process comprising the following process steps: where R1 is selected from —(C1-C12)-alkyl, —O—(C1-C12)-alkyl, —O—(C6-C20)-aryl, —(C6-C20)-aryl, —(C3-C12)-cycloalkyl, —(C3-C12)-heterocycloalkyl, —(C3-C20)-heteroaryl; R2 is selected from —(C6-C20)-aryl, —(C3-C12)-cycloalkyl, —(C3-C12)-heterocycloalkyl, —(C3-C20)-heteroaryl; R3 is —(C3-C20)-heteroaryl; and R1, R2 and R3 may each independently be substituted by one or more substituents selected from —(C1-C12)-alkyl, —(C3-C12)-cycloalkyl, —(C3-C12)-heterocycloalkyl, —O—(C1-C12)-alkyl, —O—(C1-C12)-alkyl-(C6-C20)-aryl, —O—(C3-C12)-cycloalkyl, —S—(C1-C12)-alkyl, —S—(C3-C12)-cycloalkyl, —COO—(C1-C12)-alkyl, —COO—(C3-C12)-cycloalkyl, —CONH—(C1-C12)-alkyl, —CONH—(C3-C12)-cycloalkyl, —CO—(C1-C12)-alkyl, —CO—(C3-C12)-cycloalkyl, —N—[(C1-C12)-alkyl]2, —(C6-C20)-aryl, —(C6-C20)-aryl-(C1-C12)-alkyl, —(C6-C20)-aryl-O—(C1-C12)-alkyl, —(C3-C20)-heteroaryl, —(C3-C20)-heteroaryl-(C1-C12)-alkyl, —(C3-C20)-heteroaryl-O—(C1-C12)-alkyl, —COOH, —OH, —SO3H, —NH2, halogen.
