実験手順

A mixture of (1S,2S,5R)-2-[3-(2-methyl-5-m-tolyl-thiazole-4-carbonyl)-7,7-difluoro-3-azabicyclo[3.3.0]oct-2-ylmethyl)-isoindole-1,3-dione (130 mg), hydrazine monohydrate (0.078 mL) in EtOH (10 mL) was stirred at reflux for 1 h 45. After cooling to RT, the reaction mixture was concentrated in vacuo, dissolved in DCM, washed twice with water, brine, dried (MgSO4), filtered and concentrated to yield the title compound (90 mg, 92%) as a colorless oil which was used for the next step without further purification. LC-MS: tR=0.79 min; [M+H]+=392
