Procedure
To a solution of iv (480 g, 1.73 mol) in acetone (10 L) was added benzoylisothiocyanate (280 mL, 2.08 mol) at RT and the mixture stirred for 45 min. The acetone was distilled off and hexane (2 L) added and the mixture concentrated to dryness. To the residue was added hexane (4 L) and the mixture heated to 40° C. for 30 min The solid was collected by filtration and washed with hexane (2×2 L) to obtain v (648 g, 85%).
