Reaction Steps
Dissolved 3-[(3,4-dimethoxy-benzoylamino)-methyl]-benzoic acid (100 mg, 0.317 mmol), EDC (105 mg, 0.55 mmol) and hydroxybenzotriazole (84.2 mg, 0.55 mmol) in 1 mL of DMF. The mixture was stirred for 1 h. To this was added DIPEA (0.12 mL, 0.64 mmol) and 5-methyl-4,5,6,7-tetrahydro-thiazolo[5,4-c]pyridin-2-ylamine (107 mg, 0.63 mmol). The mixture was placed in a 60° C. bath with an Ar stream blowing over it. The mixture stirred 14 h resulting in a concentrated residue. LC-MS analysis indicated the desired product. Dissolved in 5 mL of DMF/H2O and purified via prep HPLC (5%-95% CH3CN/H2O) to give 121.9 mg of 3,4-dimethoxy-N-[3-(5-methyl-4,5,6,7-tetrahydro-thiazolo[5,4-c]pyridin-2-ylcarbamoyl)-benzyl]-benzamide. MS, electrospray 467.4 (M+H).
