実験手順
Potassium 5-methyl-[1,3,4]oxadiazole-2-carboxylate (31.8 mg, 0.19 mmol) was mixed with acetonitrile (195 μl). A slurry was formed. The mixture was cooled to 0-5° C. oxalyl chloride (14.99 μl, 0.17 mmol) was added and the reaction was stirred for 1 h at 0-5° C. (1R,2S)-1-(1-(4-fluorophenyl)-1H-indazol-5-yloxy)-1-(3-methoxyphenyl)propan-2-amine (6a, 25 mg, 0.06 mmol) was dissolved in dry THF (400 μl). N,N-diisopropylethylamine (65.6 μl, 0.38 mmol) was added. The THF solution was cooled to 0-5° C. The acid chloride slurry was drop wise added to the amine solution. The reaction was stirred at 0-5° C. After 1.5 h the reaction was poured into a mixture of EtOAc and diluted ammonia (ca 5%). The mixture was shaken, the organic layer collected. The water phase was washed twice with EtOAc. The combined organic layers were dried over sodium sulphate.
