Reaction Steps
The title compound was prepared according to general procedure AT using ethyl 3-({cyclopropyl[(4-methoxy-2,6-dimethylphenyl)sulfonyl]amino}methyl)-1,2,4-oxadiazole-5-carboxylate (30 mg, 0.07 mmol), 1-[3-(pyrrolidin-1-yl)propyl]piperazine (31 mg, 0.16 mmol) and trimethylaluminium (2 M in toluene, 0.07 mL) in DCE (3 mL). The crude product was purified using prep method C, then FCC, eluting with 95:4.5:0.5 DCM:MeOH:NH3, to afford the title compound.
