Reaction Steps

25 g of trans-4-aminocyclohexanol hydrochloride were suspended in 250 mL of dry dioxane and 30 mL of sodium methylate solution (30% in methanol, 1 equivalent) were added. 39.3 mL of ethyl trifluoroacetate were added and the reaction mixture was allowed to stir until the reaction was complete. The reaction mixture was evaporated, taken up in 50 mL of 0.1 N HCl and extracted several times with dichloromethane:isopropanol 3:1. The combined organic layer was extracted once with 0.1 N HCl and brine, dried over sodium sulfate and evaporated to dryness to yield 29.0 g of 148. Rt=0.69 min (Method C). Detected mass: 212.2 (M+H+).
