10.3 g of thiomorpholine (27) was added dropwise to a mixture of 47.1 g of sarsasapogenin acrylate (28) and 200 g. of tetrahydrofuran. The mixture was stirred at room temperature for 3 hours, after which tetrahydrofuran was distilled off. Subsequent purification by silica gel column chromatography gave 56.2 g of sarsasapogenin [3-(thiomorpholino)propionate] (Quencher 7). Yield 98%.
