実験手順

4-[5-(Chloromethyl)-1H-tetrazol-1-yl]-2-(trifluoromethyl)benzonitrile (Intermediate 24, 86 mg, 0.3 mmol) and 3,5-dimethyl-1-(methylsulfonyl)piperazine (Intermediate 36, 78 mg, 0.41 mmol) were weighed into a vial and suspended in acetonitrile (1.2 mL). Triethylamine (84 μL, 0.60 mmol) was added, and the mixture was heated at 140° C. in a microwave with stirring for 3 h. The reaction mixture was applied to a 10 g SCX cartridge, pre-washed with MeOH (50 mL). This was eluted with MeOH (100 mL) and 10% aq NH3 in MeOH (100 mL). The basic fractions were concentrated to give an off-white solid (137 mg). This was purified by MDAP to give the title compound as a colourless solid (38 mg), confirmed by NMR to be the pure cis-isomer.
