Participants

Reaction Steps

To a stirred solution of 70 mg (0.14 mmol) of (RS,SR)-5-[benzenesulfonyl-(7-chloro-1,2,3,4-tetrahydro-cyclopenta[b]indol-2-yl)-fluoro-methyl]-[1,2,4]oxadiazole-3-carboxylic acid methyl ester in 3 mL of EtOH, were added 0.5 mL of an ammonium hydroxide solution (25% in water) and stirred over night. The reaction mixture was partitioned between EtOAc and water. The organic phase was dried over Na2SO4, filtered and evaporated. Recrystallisation in Et2O afforded 60 mg (86%) of (RS,SR)-5-[benzenesulfonyl-(7-chloro-1,2,3,4-tetrahydro-cyclopenta[b]indol-2-yl)-fluoro-methyl]-[1,2,4]oxadiazole-3-carboxylic acid amide as a light orange crystals, MS: 475 (MH+).
