Reaction Steps

The title compound was prepared according to general procedure AH using 2-({cyclopropyl[(4-methoxy-2,6-dimethylphenyl)sulfonyl]amino}methyl)-1,3-oxazole-4-carboxylic acid (38 mg, 100 mop, EDCI (23 mg, 120 mop, HOBt monohydrate (18 mg, 120 μmol), DIPEA (69 μL, 400 mol), tert-butyl 3-(2-aminoethyl)piperidine-1-carboxylate (23 mg, 100 μmol) and DMF (750 L). The resulting crude compound was purified by FCC eluting with 100% EtOAc to afford tert-butyl 3-[2-({[2-({cyclopropyl[(4-methoxy-2,6-dimethylphenyl)sulfonyl]amino}methyl)-1,3-oxazol-4-yl]carbonyl}amino)ethyl]piperidine-1-carboxylate. Yield: 38 mg, 64%.
