| titleOfInvention | PROCESS FOR THE PREPARATION OF AZABICYLIC COMPOUNDS |
| abstract | This invention relates to a process for the preparation of a compound of formula I or a pharmaceutically acceptable salt thereof: <IMAGE> in which Z is e.g. a -C(R7)=NR6 group in which R6 is an OR8 group, where R8 is e.g. C1-4 alkyl. It is essentially characterized in that it comprises the cyclization of a compound of formula II: <IMAGE> in which A represents Z or a group which withdraws electrons which can be converted into it, L is a separable group and R13 represents hydrogen or an N-protector group, and subsequently, optionally or as necessary, removing any R13 protector group, conversion of A into Z, interconversion of Z and/or formation of a pharmaceutically acceptable salt. |
