Reaction Steps

2-Bromothiazole-5-carboxylic acid (0.4 g, 1.923 mmol), 3-(1H-imidazole-1-yl)propan-1-amine (0.265 g, 2.115 mmol), and benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (BOP) (0.935 g, 2.115 mmol) were mixed in dichloromethane (7 ml), treated with Hunig's base (0.705 ml, 4.04 mmol) and stirred at 25° C. for 2 hours. The reaction mixture was diluted with dichloromethane and washed with water and brine. The organic layer was dried (MgSO4), filtered and concentrated. Purification by flash chromatography (silica gel, 2-20% methanol/dichloromethane) afforded the title compound.
