Procedure

The present invention provides a process for preparing 5-acetamido-3,5,7-trideoxy-7-fluoro-D-glycero-1-D-lacto-2-nonulopyranosidonic acid comprising hydrogenating benzyl 2-azido-2,4-dideoxy-4-fluoro-β-D-mannopyranoside in the presence of acetic anhydride to obtain N-acetyl-4-deoxy-4-fluoro-D-mannosamine, and subsequently reacting the product with sodium piruvate, bovine serum albumin and aldolase sialate.
