摘要 |
Novel Process and Intermediates. A process for preparing a compound of formula (I) where R<SUP>4 </SUP>and R<SUP>5 </SUP>are as defined in the specification; and R<SUP>6 </SUP>is hydrogen or a protecting group, which process comprises cyclisation of a compound of formula (II) where R<SUP>4 </SUP>and R<SUP>5 </SUP>and R<SUP>6 </SUP>are as defined in relation to formula (I), and R<SUP>7 </SUP>is nitrogen protecting group, and removing the group R<SUP>7</SUP>, and thereafter if desired, removing any protecting group R<SUP>6</SUP>.
