実験手順
The title compound was prepared in accordance with the general method of Example 1, step 5 starting from (rac)-1-(5-bromopyrimidin-2-yl)-3-(2-methoxy-ethyl)-hexahydro-cyclopenta[d]imidazol-2(1H)-one (Example 5, step 3) and 1-ethynyl-2,5-difluorobenzene to yield racemic material ((+/−)-(3aRS,6aSR)-1-(2-methoxy-ethyl)-3-(5-(2,5-difluoro-phenyl-ethynyl-pyrimidin-2-yl)-hexahydro-cyclopentaimidazol-2-one as a light brown solid; MS: m/e=399.2 (M+H+). Separation using chiral HPLC and similar separation conditions as described in example 1 yielded the enantiomerically pure enantiomers (−)-(3aR,6aS)-1-(2-methoxy-ethyl)-3-(5-(2,5-difluoro-phenylethynyl-pyrimidin-2-yl)-hexahydro-cyclopentaimidazol-2-one as an off-white solid; MS: m/e=399.2 (M+H+) and (+)-(3aS,6aR)-1-(2-methoxy-ethyl)-3-(5-(2,5-difluoro-phenylethynyl-pyrimidin-2-yl)-hexahydro-cyclopentaimidazol-2-one as a light yellow oil which solidified on standing; MS: m/e=399.2 (M+H+).
