Abstract:
A process for preparing a diazabicyclooctane compound represented by the following formula (I): wherein A represents RcO—; B represents NH or NC 1-6  alkyl; C represents a benzyl group; Rc represents a C 1-6  alkyl group; A is substituted with one substituent Fn1, wherein Fn1 represents an azetidine group; the process including: (a) silylating the compound represented by the following formula (IV-c): wherein in the formula (IV-c), OBn represents benzyloxy, and (b) carrying out an intramolecular urea formation reaction.

Claim (Index 6):
A process for preparing (2S,5R)\u2014N-(2-aminoethoxy)-7-oxo-6-(sulfooxy)-1,6-diazabicyclo[3.2.1]octane-2-carboxamide represented by the following formula (III-059): which comprises: among the compounds represented by the following formulae (IIa-Boc-059) and (IIa-Cbz-059): wherein in the formula (IIa-Boc-059) or (IIa-Cbz-059), Boc represents tert-butoxycarbonyl, Cbz represents benzyloxycarbonyl, and OBn represents benzyloxy, removing the benzyl of the benzyloxy group at the 6-position of the compound represented by the formula (IIa-Boc-059) in the presence of palladium-carbon under a hydrogen atmosphere, or removing the benzyl of the benzyloxy group at the 6-position of the compound represented by the formula (IIa-Cbz-059) in the presence of palladium-carbon under a hydrogen atmosphere in the presence of di-tert-butoxydicarbonate, and simultaneously carrying out a tert-butoxycarbonylation to prepare a compound represented by the following formula (IIb-Boc-059): wherein in the formula (IIb-Boc-059), Boc represents a tert-butoxycarbonyl group, sulfating the hydroxyl group at the 6-position of the formula (IIb-Boc-059) by a sulfur trioxide-pyridine complex in the presence of pyridine, 2-picoline or 2,6-lutidine, to prepare a compound represented by the following formula (III-Boc-059): wherein in the formula (III-Boc-059), Boc represents tert-butoxycarbonyl, and M represents H, pyridinium, sodium or tetrabutylammonium, and deprotecting the tert-butoxycarbonyl group by an acid selected from the group consisting of hydrochloric acid, sulfuric acid, methanesulfonic acid, trifluoroacetic acid and tetrafluoroboric acid.
