実験手順

To a mixture of 73 mg (0.1 mmol) of [18-(Isoquinolin-1-yloxy)-2,15-dioxo-4-(1-propylcyclopropanesulfonylamino-carbonyl)-3,16-diaza-tricyclo[14.3.0.04,6]nonadec-7-en-14-yl]-carbamic acid tert-butyl ester in 3 mL of methanol was added 332 mg (2 mmol)of dipotassium azodicarboxylate. Glacial acetic acid (240 mg, 4 mmol) in 2 mL of methanol was added slowly by a syringe pump over 5 h. The mixture was stirred at rt. After 5 h, another 332 mg (2 mmol) of dipotassium azodicarboxylate and 240 mg (4 mmol) of glacial acetic acid was added over the course of 5 h and the stirring was continued overnight. This cycle was repeated twice. LC-MS showed about 40% starting material still remaining. The solvent was then removed on a rotary evaporator. Water was added to the residue and the mixture was extracted three times with ethyl acetate. It was then dried with magnesium sulfate, filtered and concentrated in vacuo. The resulting oil was dissolved in methanol and purified by preparative HPLC (YMC ODS-A, S5, 20×100 mm, gradient: 80% B to 85% B, 15 min, hold 2 min, flow rate 25 mL/min) to isolate the product as a white powder (25 mg, 34%).
