Procedure

A mixture of (−)-FTC [32 (2R, β/α)] (60:40 of a β:α anomer mixture, 3.0 g) was dissolved in methanol (30 ml), cooled to 0° C., and treated with a 4.0 M solution of HCl in 1,4-dioxane (3.3 ml [1.1×]). The solution was stirred for 20 minutes, and subsequently concentrated to dryness affording an off-white solid.
