Reaction Steps

A solution of (1S,3S)-6-chloro-3-phenylindan-1-ol (Va) (17 g) (synthesized as in example 8) in tetrahydrofuran (130 ml) is cooled with an ice bath. Thionyl chloride (9.9 g) in tetrahydrofuran (50 ml) is added drop wise at 4-5° C., and then the mixture is stirred over night at ambient temperature. A mixture of water and ice (approximately 25 ml) is added, and stirring is continued until all the ice has melted. The phases are separated, and the organic phase is washed twice with sodium bicarbonate (5% in water, 25 ml). The water phases are then combined, extracted with the organic phase, and then extracted with ethyl acetate (50 ml). The organic phases are then combined, dried with magnesium sulfate, filtered, and evaporated to dryness using a rotary evaporator. Yield 18.7 g (102%) of the title compound as an oil, which partly solidifies. The content of (1S,3R)-3,5-dichloro-1-phenylindan is 18% according to NMR.
