A solution of 5-bromo-1-isopropyl-6-methyl-4-oxo-1,4-dihydro-pyridine-3-carboxylic acid (preparation 1c, 270 mg, 0.99 mmol), TBTU (316 mg, 0.99 mmol) and DIPEA (513 μL, 2.97 mmol) in DMF (3.00 mL) is stirred for 10 min at room temperature. Then, a solution of (4-(N-cyano-S-methylsulfonimidoyl)phenyl)methanamine (preparation 6, 247 mg, 1.18 mmol) in DMF (1.00 mL) is added and the reaction mixture is stirred for 18 h at room temperature. The reaction mixture is purified by preparative reversed phase HPLC (Sunfire, gradient of acetonitrile in water, 0.1% TFA, 60° C.). Yield: 70 mg (15% of theory); ESI mass spectrum: [M+H]+=465 (bromine isotope pattern); r.t. HPLC: 0.86 min (Z017_S04).
