Participants

Reaction Steps

To a mixture of trans-8-chloro-1-[4-(5-methyl-[1,2,4]oxadiazol-3-yl)-cyclohexyl]-5,6-dihydro-4H-2,3,5,10b-tetraaza-benzo[e]azulene hydrochloride (0.100 g, 0.237 mmol) and N-ethyldiisopropylamine (0.122 ml, 0.712 mmol) in dichloromethane (2.4 ml) was added 2,2-difluoroethyl trifluoromethanesulfonate (0.061 g, 0.29 mmol). After stirring for 16 h the reaction mixture was partitioned between ethyl acetate (50 ml) and 0.5 M aqueous sodium hydroxide solution (50 ml). The layers were separated. The aqueous layer was extracted with one 50 ml-portion of ethyl acetate. The combined organic layers were dried over anhydrous sodium sulfate and concentrated in vacuo. Flash-chromatography with n-heptane/2-propanol as eluent gave the title compound (0.031 g, 33%) as colorless solid. MS m/e: 449 ([M+H]+).
