| 反応物 | Hydrazine hydrate (1:1) | HCID 24654 | — |
| 反応物 | Methyl 2-methylisonicotinate | HCID 11542811 | — |
| 生成物 | 2-Methylisonicotinic acid hydrazide | HCID 322549 | 86% |
反応手順
2-Methyl-isonicotinic acid methyl ester (316.5 mg, 2.093 mmol) was dissolved in MEOH (7 mL) under Argon and hydrazine monohydrate 98% (1 mL, 20.93 mmol) was added. The reaction was allowed to stir under Argon at room temperature for eighteen hours. The reaction was concentrated to give the title compound (271.9 mg, 86%) as a white solid. 1H NMR CDCl3 δ (ppm): 8.59 (d, 1H), 7.50 (s, 1H), 7.38 (d, 1H), 3.09 (br. s, 3H), 2.60 (s, 3H).
