Reaction Steps

The title compound was prepared according to general procedure AT using ethyl 5-({cyclopropyl[(4-methoxy-2,6-dimethylphenyl)sulfonyl]amino}methyl)-1,3,4-thiadiazole-2-carboxylate (30 mg, 0.07 mmol), 1-(1-methylpiperidin-4-yl)piperazine (26 mg, 0.14 mmol) and trimethylaluminium (2 M in toluene, 0.07 mL) in DCE (5 mL). The crude product was purified using FCC, eluting with 95:4.5:0.5 DCM:MeOH:NH3, to afford the title compound.
