実験手順
Acid 84 (20 mg, 1.4 eq) in CH2Cl2 (1 mL) was treated with PyBOP (53 mg, 1.2 eq) and NMM (0.028 mL, 3.0 eq) and stirred for 5 minutes. To this was added a solution of oxalamide (50 mg, 1.0 eq) and NMM (0.028 mL, 3.0 eq) in CH2Cl2 (1 mL) and the mixture stirred at room temperature overnight. The mixture was diluted with ethyl acetate, the organic phase washed with 0.5N HCl, brine, saturated bicarbonate solution, and brine, then dried over sodium sulfate, filtered and concentrated in vacuo. Purification by preparative HPLC yielded 24 mg (38%) of N-[cyclohexyl-(1-{2-[1-cyclopropylcarbamoyl-hydroxy-methyl)-butylcarbamoyl]-octahydro-indole-1-carbonyl}-2,2-dimethyl-propylcarbamoyl)methyl]-N′-phenyl-oxalamide 96 as a white solid with consistent analytical data. LCMS ret time=4.07, M+H=737.26, M−H=735.22.
