実験手順

A solution of 0.20 g (0.52 mmol) of 4-(2-cyano-pyrrol-1-yl)-2-(1H-indole-4-sulfonylamino)-butyric acid methyl ester (from the synthesis of I-102) and 0.070 g (0.52 mmol) of NCS in 1 mL of DMF is stirred overnight, and then diluted with MeCN and purified by preparative HPLC to provide 0.15 g (0.36 mmol; 69%) of 2-(3-chloro-1H-indole-4-sulfonylamino)-4-(2-cyano-pyrrol-1-yl)-butyric acid methyl ester. This material is stirred in 1.4 mL of THF with 1.4 mL of 1M NaOH for 3 h, and then 2N HCl is added until the pH is 3. The mixture is extracted with EtOAc, and the extract washed with brine, dried over Na2SO4, filtered, and concentrated to provide 0.12 g (85%) of I-103 as a tan powder.

後処理
