In an acetic acid solution containing 2.0 g of L-indoline-2-carboxylic acid, 5% Rh/Al2O3 was added and the resultant mixture was stirred for 3 days in a hydrogen gas atmosphere (4.5 kg/cm2). The reaction mixture was filtered and the filtrate was evaporated under reduced pressure. The resultant residue was tert-butoxycarbonylated to give 0.6 g of the title compound.
