Versuchsvorschrift

A mixture of 2-(4-fluorophenyl)-4-methylpyrimidine-5-carboxylic acid (232 mg, 1 mmol) and O-(7-azabenzotriazol-1-yl)-N,N,N,N-tetramethyluronium hexafluorophosphate (380 mg 1 mmol) in dry DMF (12 mL) is treated with diisopropylethylamine (0.18 mL) and stirred at room temperature for 30 min. A solution of 3-methylsulfamoylbenzylamine (300 mg, 1.5 mmol) in dry DMF (1.5 mL) is added and the mixture is stirred at room temperature for 24 hours. The solvent is removed and the residue is partitioned between EtOAc and water. The organic phase is separated, washed with saturated NaHCO3, water and brine, dried (MgSO4), filtered and concentrated in vacuo. The residue is purified by column chromatography eluting with 60% EtOAc in heptane to afford 2-(4-fluorophenyl)-4-methylpyrimidine-5-carboxylic acid 3-methylsulfamoyl-benzylamide (210 mg, 52%) as a solid. MS: 415 (M+H); 1H NMR (300 MHz, DMSO-d6): δ 2.42 (s, 3H), 2.63 (s, 3H), 4.60 (d, 2H), 7.37-7.40 (t, 2H), 7.50 (s, 1H), 7.60-7.75 (m, 3H), 7.80 (s, 1H), 8.45-8.50 (dd, 2H), 8.88 (s, 1H), 9.30 (t, 1H).
