実験手順

2-tert-Butoxycarbonylamino-3-(3-nitropyridin-2-ylamino)propionic acid was prepared by a similar method as (2S) 2-tert-butoxycarbonylamino-3-(2-nitrophenyl-amino)propionic acid in Step A of the synthesis of 600a/103, except that 3-chloro-3-nitro pyridine was used instead of 2-fluoronitrobenzene, to give 4.05 g (64%) of a yellow solid.
