Reaction Steps

To 500 mg of methyl 6,6a-dihydro-1aH-indeno[1,2-b]oxirene-1a-carboxylate were added 860 mg of sodium azide, 309 mg of ammonium chloride, 4 ml of methanol, and 0.5 ml of water, followed by stirring at 80° C. for 2 hours. To the reaction mixture were added a saturated aqueous sodium hydrogen carbonate solution, water, and ethyl acetate to carry out a layer separation operation, and the organic layer was dried over anhydrous magnesium sulfate. To a solution of the obtained intermediate product in ethyl acetate-methanol was added 61 mg of 10% palladium-carbon (wet), followed by stirring for 6 hours under a hydrogen atmosphere. The reaction mixture was filtered over Celite and the solvent was then evaporated under reduced pressure to obtain 0.51 g of methyl rac-(1R,2R)-1-amino-2-hydroxyindane-1-carboxylate.
