Paragraph 0043-0045, (2020/09/12)
The invention provides a safe and convenient method for preparing N - [(1R, 2S, 5S) -2 - amino -5 - [(dimethylamino) carbonyl] cyclohexyl] carbamic acid tert-butyl formate. The compound N - [(1R, 2R, 5S) -5 - [(dimethylamino) carbonyl] -2 - hydroxycyclohexyl] carbamic acid tert-butyl carbamate and the DBU azidate are then reacted to obtain N - [(1R, 2R, 5S) -5 - [(dimethylamino) carbonyl] cyclohexyl] carbamic acid tert-butyl formate in the presence of DBU to obtain the corresponding amino. N - [(1R, 2S, 5S) -2 - amino -2 -5 - [(dimethylamino) carbonyl] cyclohexyl] carbamic acid tert-butyl formate in the presence of a DBU to obtain the corresponding amino compound. N - 2S [(dimethylamino) carbonyl] cyclohexyl] carbamic acid tert-butyl formate 1R 5S -2 -5 . (by machine translation)

The problem to be solved is to provide a method for efficiently producing compounds (1) and (1a) that are important intermediate compounds in the production of FXa inhibitors (X) and (X-a). The solutions thereto are a method for producing a compound represented by the formula (8d) using a stereoselective intramolecular cyclization reaction, and a method for producing a compound (1f) or a salt thereof, or a hydrate thereof, which is characterized by desulfonylation of the compound (8d). In each formula, R4a represents a C1-C6 alkyl group, a benzyl group, etc.
