N-[(3R,4R)-4-氟吡咯烷-3-基]氨基甲酸叔丁酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of (3R,4R)-benzyl 3-((tert-butoxycarbonyl)amino)-4-fluoropyrrolidine-1-carboxylate (3.0 g, 8.8 mmol) in MeOH (50 mL) was added wet Pd/C (0.3 g, 10%) under nitrogen. The suspension was degassed under vacuum and purged with hydrogen three times. The resulting mixture was stirred at rt under hydrogen balloon for 3 hr. The reaction mixture was filtered and the filtrate was concentrated to afford the title compound (1.6 g, 88% yield) as light yellow oil that solidified on standing. The suspension was degassed under vacuum purged with hydrogen three times The reaction mixture was filtered the filtrate was concentrated

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: The title compound was prepared in analogy to Example 78-1 in Scheme 7 by using 4-(4-chloro-6-methylquinolin-2-yl)-2,3,4,5-tetrahydro-1,4-benzothiazepine 1,1-dioxide and tert-butyl (trans-4-fluoropyrrolidin-3-yl)carbamate.
