Lsoindoles

Step 1 1-(p-Chlorophenyl)-3-Ethoxy-1 H-lsoindole - Crystalline triethyloxonium boron-tetrafluoride (21 g) (prepared from 23 g of borontrifluoride etherate and 11 g of epichlorohydrin) is dissolved in 100 ml of absolute methylenechloride. 3-(p-Chlorophenyl) phthalimidine (21 g) is added and the reaction mixture is stirred overnight at room temperature. The resulting solution is poured onto 50 ml of saturated Sodium carbonate, extracted with 500 ml of ether and dried. Upon evaporation of the solvent there is obtained crude material which is recrystallized from methylene chloride/hexane (1 1) to yield l-(p-chlorophenyl)-3-ethoxy-1 H-isoindole MP 102° to 103°C.
