実験手順: At −78° C., NaH (60% in mineral oil; 220 mg, 5.52 mmol, 1.1 eq) is added to a solution of 2-chloro-1H-indole x160 (0.76 g, 5.02 mmol, 1 eq) in dry DMF (50 ml). The temperature is raised to −20° C. during 20 minutes, then 1-(chloromethyl)-4-propylpyrrolidin-2-one x63 (0.76 g, 5.02 mmol, 1 eq) dissolved in DMF (10 ml) is added drop wise. After 2 hours at room temperature, water (50 ml) is added. The aqueous layer is extracted with CH2Cl2 (3×30 ml). The combined organic layers are dried on anhydrous MgSO4, filtered off and concentrated under reduced pressure to obtain a liquid that is purified on silicagel (AcOEt/Benzine 1/9) yielding 1-[(2-chloro-1H-indol-1-yl)methyl]-4-propylpyrrolidin-2-one 274 as a colorless liquid (605 mg). is added drop wise The aqueous layer is extracted with CH2Cl2 (3×30 ml) The combined organic layers are dried on anhydrous MgSO4 filtered off concentrated under reduced pressure to obtain a liquid that is purified on silicagel (AcOEt/Benzine 1/9)

実験手順: At room temperature, POCl3 (1 ml, 10.82 mmol, 2 eq) is added to a well stirred suspension of N,N-diethylaniline (1 ml, 5.41 mmol, 1 eq) and 1,3-dihydro-2H-indol-2-one x159 (0.72 g, 5.41 mmol, 1 eq) in dry toluene (15 ml). The mixture is heated at reflux during 3 hours. After cooling, water (15 ml) is carefully added and the organic layer is washed with water (3×25 ml). The organic layer is dried on anhydrous MgSO4, filtered off and concentrated under reduced pressure to obtain 0.76 g of 2-chloro-1H-indole x160 as an orange solid (0.76 g, 93%). The mixture is heated at reflux during 3 hours After cooling the organic layer is washed with water (3×25 ml) The organic layer is dried on anhydrous MgSO4 filtered off concentrated under reduced pressure
