Participants

Reaction Steps

(3-amino-2-oxo-2,3,4,7-tetrahydroazepin-1-yl) acetic acid methyl ester, 3, (0.365 g, 1.68 mmol) is dissolved in 1:1 CH2Cl2/DMF and 1-isoquinoline-carboxylic acid (1.4 g, 8.1 mmol), 1-hydroxybenzotriazole (0.35 g, 2.6 mmol), and 1-(3-dimethyl-aminopropyl)-3-ethyl-carbodiimide hydrochloride (0.5 g, 2.6 mmol) are added. The resulting solution is stirred at room temperature for 12 hours, diluted with EtOAc, washed with saturated NaHCO3 then brine, and dried (MgSO4). The solvent is removed in vacuo and the resulting residue is purified over silica gel (EtOAc/hexane) to afford the desired product.
