実験手順
A mixture of 207 mg (0.6 mmol) of tert-butyl[(1R)-3-hydrazino-3-oxo-1-(2,4,5-trifluorobenzyl)propyl]carbamate (Intermediate 4), 110 mg (0.5 mmol) of 3-(trifluoromethyl)-6,7-dihydro[1,2,4]triazolo[4,3-a]pyrazine-8(5H)-thione (Intermediate 6), and 5.5 mL of methanol was stirred at reflux for 1 day. Diethyl ether was added to the cooled solution, resulting in precipitation. The solid was removed by filtration, and the filtrate was concentrated to dryness. Purification of the residue by preparative HPLC (C18 reverse phase column, 30-80% acetonitrile in water containing 0.05% trifluoroacetic acid) afforded the title compound. LC-MS 536 (M+1).
