Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Methylamine tetrahydrofuran | HCID 66615946 | — |
| Reactant | 2-(Methylsulfonyl)-5-[3-[3-(trifluoromethoxy)phenyl]-1-benzofuran-5-yl]-1,3,4-oxadiazole | HCID 68664235 | — |
| Product | N-methyl-5-[3-[3-(trifluoromethoxy)phenyl]-1-benzofuran-5-yl]-1,3,4-oxadiazol-2-amine | HCID 68663394 | 67% |
Reaction Steps
In the same manner as in Example 110 and using 2-(methylsulfonyl)-5-[3-[3-(trifluoromethoxy)phenyl]-1-benzofuran-5-yl]-1,3,4-oxadiazole instead of 2-(2,3-dihydro-1-benzofuran-5-yl)-5-(methylsulfonyl)-1,3,4-oxadiazole and using 2M methylamine-tetrahydrofuran solution instead of 3-fluorobenzylalcohol, the title compound (yield 67%) was obtained as colorless crystals.
