実験手順

To a solution of methyl 5-(2-aminophenyl)-6-cyclohexyl-4H-thieno[3,2-b]pyrrole-2-carboxylate obtained in Step 9, sodium acetate (2.4 g, 29 mmol) and acetic acid (1.7 ml, 29 mmol) in tetrahydrofuran (70 ml) was added chloroacetyl chloride (2.3 ml, 29 mmol) under ice-cooling. After stirring at room temperature for 2 hr, the reaction mixture was concentrated under reduced pressure. Water (100 ml) was added to the obtained solid. The solid was collected by filtration, washed with diethyl ether (20 ml×2), and dried under reduced pressure to give methyl 5-[2-(2-chloroacetylamino)phenyl]-6-cyclohexyl-4H-thieno[3,2-b]pyrrole-2-carboxylate (5 g, yield after 2 steps from Step 9: 58%).
