methyl 2,3,4,5,6,6a-hexahydro-1H-cyclopenta[c]pyrrole-3a-carboxylate

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To the solution of methyl octahydrocyclopenta[c]pyrrole-3a-carboxylate (1.0 g, 5.91 mmol) in EtOH (10.0 mL) was added DIPEA (2.80 mL, 16.12 mmol) at rt and the mixture stirred at rt for 10 min followed by addition of 5-bromo-2-chloropyrimidine (1.10 g, 5.37 mmol). The reaction was heated up to 70° C. for 2 h. After completion (by TLC), solvent was evaporated and the crude residue purified over 100-200 M silica-gel using 7.0% EtOAc:hexane to obtain the desired product as a white solid (0.80 g, 45%). MS: 326.19 [M+H]+. The reaction was heated up to 70° C. for 2 h After completion (by TLC), solvent was evaporated the crude residue purified over 100-200 M silica-gel

実験手順: To a stirred solution of methyl 2-benzyloctahydrocyclopenta[c]pyrrole-3a-carboxylate (2.0 g, 7.69 mmol) in MeOH (15.0 mL) was added palladium hydroxide (0.20 g, 10% w/w) and the mixture stirred at rt for 16 h under H2 atmosphere. After completion of reaction (by TLC), the reaction mixture was passed through celite and the solvent evaporated. The crude (1.50 g) residue was carried forward for the next step without further purification. MS: 170.18 [M+H]+. After completion of reaction (by TLC) the solvent evaporated The crude (1.50 g) residue was carried forward for the next step without further purification
