| 생성물 | 7-Azabicyclo[2.2.1]hepta-2,5-diene-2,3,7-tricarboxylic acid 2,3-dimethyl 7-tert-butyl ester | HCID 14085413 | 50% |
반응 단계
Freshly distilled acetylenedicarboxylic acid dimethyl ester (6.7 mL, 54 mmol) and N-(tert-butyloxycarbonyl)-1H-pyrrole (9.0 mL, 54 mmol) were combined and heated at 120° C. for 3 h. Purification by flash chromatography on SiO2 eluting with EtOAc/CH2Cl2 gave 8.3 g (27 mmol, 50%) of compound 31A as a yellow solid.
