Thiazolidine → 3-(2-Fluoro-4-nitrophenyl)thiazolidine
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Thiazolidine | HCID 10444 | — |
| Reactant | Diisopropylethylamine | HCID 81531 | — |
| Reactant | 1,2-Difluoro-4-nitrobenzene | HCID 123053 | — |
| Product | 3-(2-Fluoro-4-nitrophenyl)thiazolidine | HCID 53938969 | 24% |
Reaction Steps
Using the same general procedure as step 1, of Example 1, 4.092 g (45.90 mmol) thiazolidine was treated with 4.1 mL (37.03 mmol) 3,4-difluoronitrobenzene and 10.0 mL (57.41 mmol) N,N diisopropylethyl amine to provide 2.020 g (24%) of the title compound as an orange solid. Recystallization from methylene chloride/hexane provided an analytical sample with a melting point of 94°-95° C.
