  White to off-white powder

• Synthesis

  Put 50g of benzyl ((3aS,4R,6S,6aR)-6-(2-hydroxyethoxy)-2,2-dimethyltetrahydro-4H-cyclopenta[d][1,3]dioxol-4-yl)carbamate and 250 mL of methanol into a 1L four-necked flask 1.Add 10 g of 10% palladium carbon and 22.4 g of ammonium formate to bottle 1 at 20-30°C. After the addition, the temperature is raised to 40-50°C, and the reaction is stirred for 10 hours and filtered with suction. The filtrate was transferred to a 1L four-neck flask 2, and the temperature was raised to 40-50°C again. 21.4g L-tartaric acid was added to batches 2 while stirring. Then, continue to stir the reaction for 1 hour, slowly lower the temperature to 10-20°C, and stir the reaction for 2 hours, and a large number of white solids can be seen to precipitate. Continue to lower the temperature to 0-10°C and react for 0.5h, then suction filter and wash the filter cake once with 50mL ethanol. The filter cake was dried under reduced pressure at 40° C. for 4 hours to obtain 45.7 g of white powdery solid 2-((3aR,4S,6R,6aS)-6-amino-2,2-dimethyltetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-yloxy)ethanol L-tataric acid with a yield of 87.47%.
