tert-butyl N-(3-azabicyclo[4.1.0]heptan-1-yl)carbamate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: According to the procedure of Example 34A, 1-tertbutoxycarbonylamino-3-azabicyclo[4.1.0]heptane (270.0 mg, 1.27 mmol) and 1-cyclopropyl-6,7-difluoro-1,4-dihydro-4-oxo-quinoline-3-carboxylic acid (275.6 mg, 1.03 mmol) were reacted to generate the title compound (304.2 mg, 0.666 mmol, 65%). were reacted

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 1-tert-butoxycarbonylamino-3-azabicyclo-[4.1.0]heptane (200 mg, 0.94 mmol) and the ethyl ester of 7-chloro-6-fluoro-1-(2,4-difluorophenyl)-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic acid (327 mg, 0.85 mmol) in acetonitrile (12 ml) was heated at reflux for 3 hours. Solvent was removed in vacuo, and the residue was chromatographed on silica gel (eluant: 50% ethyl acetate/hexane) to afford the title product as an off-white solid (423 mg, 0.758 mmol, 88% yield). at reflux for 3 hours Solvent was removed in vacuo the residue was chromatographed on silica gel (eluant: 50% ethyl acetate/hexane)

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
