実験手順

A catalytic amount of Pd(Ph3P)4 is added to a solution of (2-ethoxy-5-oxo-tetrahydrofuran-3-yl)-carbamic acid allyl ester (338 mg, 1.48 mmol) and N,N-dimethylbarbituric acid (483 mg, 3.1 mmol) in CH2Cl2 (5 mL) at room temperature. The solution is stirred for 15 min then {3-[(isoquinolin-1-carbonyl)amino]-2-oxo-2,3,4,7-tetrahydro-azepin-1-yl} acetic acid, 5, (178 mg) as prepared above is added as a solution in CH2Cl2 (1 mL) followed by 1-hydroxybenzotriazole (416 mg, 3.1 mmol) and 1-(3-dimethyl-aminopropyl)-3-ethyl-carbodiimide hydrochloride (584 mg, 3.1 mmol). The solution is stirred for an additional 3 hours, then diluted with EtOAc, washed with saturated NaHCO3, brine, dried (MgSO4), and concentrated in vacuo to afford the desired product in sufficient purity to be used directly.
