Procedure

A suspension of 2,2,2-trichloroethyl 5-tert-butyl-3-(hydroxymethyl)-2-methoxyphenylcarbamate (1.50 g, 3.90 mmol), (1S,2R)-2-amino-2,3-dihydro-1H-indene-1-ol.L-tartaric acid salt (1.28 g, 4.29 mmol) and N,N-diisopropylethylamine (2.37 mL, 13.6 mmol) in acetonitrile (19.5 mL) was heated to reflux. After 17 hours, the mixture was allowed to cool and the reaction solution was concentrated under reduced pressure. The obtained residue was purified by column chromatography (silica gel, hexane/ethyl acetate=50/50-0/100) to obtain 1.09 g of the captioned compound (73% yield).
