Procedure

A solution of sodium methylsulfinylmethide is produced from 0.7 g of (50%) sodium hydride and 15 ml of dimethylsulfoxide as in Example 1c. A solution of 4.2 g of 4-(4-chlorobenzylthio)-4-(2-fluorophenyl)-1-methylpiperidine, free base of a, in 15 ml of dimethylsulfoxide is added to this solution over a three minute span. After total addition, the mixture is stirred at ambient temperature for one hour and then poured onto 70 ml of ice-water. The mixture is diluted with water to 120 ml total volume before being filtered to collect the crude product. The product is washed with water and then dissolved with ether. The ethereal solution is sequentially washed thrice with water and once with a saturated sodium chloride solution and dried to give yellow-white crystals. The crystals are chromatographed with ether through an alumina column to give white crystals, mp 121°-123° C. of 3-(4-chlorophenyl)-1,3-dihydro-1'-methylspiro[benzo(c)thiophene-1,4'-piperidine].
