関与物質
| 役割 | 名称 | HCID | 仕込み量 |
|---|---|---|---|
| 反応物 | 1,3-Dichloroacetone | HCID 10793 | — |
| 反応物 | 3-Methylthiophene-2-carboxamide | HCID 588128 | — |
| 生成物 | 4-Chloromethyl-2-(3-methyl-2-thienyl)oxazole | HCID 22009832 | 61% |
反応手順
In substantially the same manner as in Reference Example 47, 3-methyl-2-thiophenecarboxamide was allowed to react with 1,3-dichloroacetone to give 4-chloromethyl-2-(3-methyl-2-thienyl)oxazole. The yield was 61%. Recrystallization from ethyl acetate-hexane gave colorless needles, mp 95-96° C.
