실험 절차

Of the compound from Example 177A, 162 mg (0.46 mmol), 145 mg (0.51 mmol) of the compound from Example 153A, 107 mg (0.56 mmol) of EDC, 75 mg (0.56 mmol) of HOBt and 97 μl (0.56 mmol) of N,N-diisopropylethylamine were stirred in 5.4 ml of DMF at RT overnight. The solution was diluted with 150 ml of ethyl acetate and extracted in succession twice each with 1M hydrochloric acid and with 1M aqueous sodium hydrogen carbonate solution. The organic phase was dried over sodium sulphate and freed from the volatile components on a rotary evaporator. The residue was purified by preparative HPLC [Method 20]. The product fraction was freed from the solvents on a rotary evaporator and the residue was dried in an HV. This gave 163 mg (61% of theory) of the title compound.
