4-Toluenesulfonyl chloride → HCID 87938282, compound

Participants

Reaction Steps

A solution of (6S)-(7,8-dihydro-6H-5-oxa-1-aza-phenanthren-6-yl)-methanol (0.14 g, 0.65 mmole) and p-toluenesulfonyl chloride (0.25 g, 1.3 mmole) in anhydrous pyridine (50 mL) was allowed to stir for 24 hours and then the solvent was removed in vacuum. The residue was dissolved in ethyl acetate (50 mL) and washed with water (3×30 mL). The organic layer was dried over sodium sulfate and filtered, and the solvent was removed under vacuum. Column chromatography on silica gel (50% methylene chloride/hexane) afforded 0.23 g (96%) of the title compound as a solid, mp 123° C., [α]25D=+51.22° (4.92, CHCl3).
