Hydrazine hydrate (1:1) → HCID 68406318, compound
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydrazine hydrate (1:1) | HCID 24654 | — |
| Reactant | HCID 59186967 | HCID 59186967 | — |
| Solvent | 1-Butanol | HCID 263 | — |
| Product | HCID 68406318 | HCID 68406318 | 72% |
Reaction Steps
As described for example 112a, (6-methyl-pyridin-3-yl)-acetic acid ethyl ester in butanol was reacted with hydrazine hydrate (2 equivalents) and the resulting mixture was then heated under reflux for 20 h. Evaporation of all volatiles and crystallization from n-butanol and toluene afforded the title compound as a white solid (yield: 72%). 1H-NMR (300 MHz, DMSO): δ=2.42 (s, 3H), 3.32 (s, 2H), 4.21 (s, 2H), 7.17 (d, J=8 Hz, 1H), 7.53 (dd, J=2 Hz, J=8 Hz, 1H), 8.30 (d, J=2 Hz, 1H), 9.23 (s, 1H).
