実験手順: Weigh 29.0 mg [3-(2,2-dimethylpropanoyl)-6-methoxy-1H-indazol-1-yl]acetic acid, 23.0 mg HOBt, and 38.3 mg EDC into a 13×100 mm screw cap tube. Add 17.3 mg N-propylbutylamine followed by 1 mL DMF and 45.2 mg DIEA in that order. The mixture was stirred at 45° C. for two hours and purified by RP-HPLC using 65-100% MeCN gradient. The pure product fractions were pooled and lyophilized to give the title compound as white solid. LC-MS: 4.20 min. (m/Z=388.3, 410.3). purified by RP-HPLC using 65-100% MeCN gradient

実験手順: Dissolve a mixture of 17 mg [2-(2,2-dimethylpropanoyl)-5-methoxy-1-benzofuran-3-yl]acetic acid from the Step B Example 1 and 18.5 mg HOBt in 1 mL dry DMF. Add 13.6 μL N-propylbutylamine followed by 23.0 mg EDC and 35 μL DIEA. This solution was heated at 40° C. for 2 hours. It was purified directly on RP-HPLC using 65-100% MeCN gradient. The fractions containing pure product were pooled and lyophilized to give the title compound. LC-MS: 4.31 min. (m/Z=304.2, 388.2, 410.2). Dissolve It was purified directly on RP-HPLC using 65-100% MeCN gradient The fractions containing pure product
