実験手順

A solution of 2-amino-5-(3-cyclopropylsulfamoyl-phenyl)-N-methoxy-N-methyl-nicotinamide (Intermediate GA) (0.08 g, 0.21 mmol) in THF (3 ml) is cooled to 0° C. 2M 4-tert Butyl phenyl magnesium bromide in THF (0.32 ml, 0.64 mmol) is added dropwise, and the resulting solution is stirred and allowed to warm to room temperature overnight. The reaction is quenched with 2M HCl (5 ml). The solvent is removed in vacuo and the residue purified by reverse phase column chromatography (Isolute™ C18, 0-100% MeCN in water −0.1% TFA). The solid obtained is dissolved in DCM, washed with 2M NaOH. The solvent is removed in vacuo and the resulting solid is dried in vacuo at 40° C. overnight to yield the title compound. 1H NMR (400 MHz, DMSO-d6) δ 8.69 (1H, d), 8.01 (1H, d), 7.97-7.89 (3H, m), 7.78 (1H, d), 7.72-7.67 (5H, m), 7.64 (2H, d), 2.18-2.13 (1H, m), 1.38 (9H, s), 0.47-0.38 (4H, m); MS m/z 450 [M+H]+
