実験手順

2-(5,6-Difluoro-benzothiazol-2-ylamino)-1-methyl-1H-benzoimidazole-5-carboxylic acid methylamide (26 mg) was prepared by following General Procedure F using 2-(5,6-Difluoro-benzothiazol-2-ylamino)-1-methyl-1H-benzoimidazole-5-carboxylic acid (36 mg), methylamine (0.2 ml, 2.0 M solution in THF), HBTU (38 mg), and DIEA (0.2 ml). LCMS: m/z 375; and 1H NMR (DMSO-d6, 400 MHz): δ 8.30 (d, 1H), 8.04 (s, 1H), 7.93 (d, 1H), 7.60 (d, 1H), 7.49 (m, 2H), 7.29 (d, 1H), 3.62 (s, 3H), and 2.80 (d, 3H).
