(S)-4-(Oxiran-2-ylmethoxy)benzonitrile → tert-Butyl 7-[(2S)-3-(4-cyanophenoxy)-2-hydroxypropyl]-9-oxa-3,7-diazabicyclo[3.3.1]nonane-3-carboxylate

Participants

Reaction Steps

A mixture of tert-butyl 9-oxa-3,7-diazabicyclo[3.3.1]nonane-3-carboxylate (prepared in an analogous fashion to the compound of Preparation A(vi) above; 0.72 g, 3.2 mmol) and 4-[(2S)-oxiranylmethoxy]benzonitrile (from step (i) above; 0.56 g, 3.2 mmol) in IPA/water (11 mL of 10:1) was stirred at 60° C. for 18 h. The solvent was then evaporated to give 1.3 g (100%) of the sub-title compound, which was used in the next step without further purification.
