The reaction of 2,3-dichloropyrazine (I) with hexanethiol (II) by means of NaH in DMF/THF gives 2-chloro-3-(hexylsulfanyl)pyrazine (III), which is condensed with rac-exo-1-azabicyclo[2.2.1]heptan-3-ol (IV) by means of NaH in THF afforing the target compound as a racemic mixture that is submitted to optical resolution with tartaric acid. The intermediate -exo-1-azabicyclo[2.2.1]heptan-3-ol (IV) has been obtained as follows: The reduction of 1-azabicyclo[2.2.1]heptan-3-one (V) with H2 over PtO2in ethanol gives the corresponding endo-alcohol (VI), which is esterified under Mitsunobu conditions (PPh3, diisopropyl azodicarboxylate (DIAD) and benzoyl chloride) yielding the exo-benzoate (VII). The hydrolysis of (VII) with sodium methoxide in methanol affords the target exo-alcohol (IV).
