実験手順

In a similar manner to the procedures described in Preparative Examples 5(i)′ and 5(ii) above, reduction, methanesulfonylation and cyanogenation were conducted, using (S)-1-benzyloxycarbonyl-4-methylideneproline methyl ester [obtained as described in Preparative Example 8(i)′ above], instead of methyl 1-benzyloxycarbonylindoline-2-carboxylate, to give the title compound as a colorless oil (yield: 61%).
