Reaction Steps

Novozym 435 (Aldrich Corp., 1.0 g) was added to a mixture of trans-1-amino-2-methylindane (6.6 g, 0.0448) and methyl 2-methoxyacetate (5.04 g 0.0484 mol) in tert-butyl methyl ether. The mixture was heated at reflux for 2 hours, a further amount of Novozym 435 (0.5 g) added and heating is continued for an additional 2 hours. Dichloromethane was added to the cooled mixture and the biocatalyst filtered off. The organic layer was dried (sodium sulfate), evaporated and the residue dissolved in the minimum of dichloromethane. A solution of ethanolic hydrochloric acid (8N) was added and the solid filtered to give (1S,2R)-1-amino-2-methylindane hydrochloride, and the filtrate evaporated to give N-[(1R,2S)-2-methyl-1-indanyl]-2-methoxyacetamide (5.9 g), m.p. 78-79° C.
