| Reactant | (S)-tert-Butyl 4-(5-(5-Bromo-1-methyl-2-oxo-1,2-dihydropyridin-3-ylamino)pyrazin-2-yl)-3-methylpiperazine-1-carboxylate | HCID 86684429 | — |
| Product | (S)-5-Bromo-1-methyl-3-(5-(2-methylpiperazin-1-yl)pyrazin-2-ylamino)pyridin-2(1H)-one | HCID 86684430 | 97% |
Reaction Steps
A mixture of 230d (1.9 g, 3.97 mmol) and trifluoroacetic acid (4 mL) was stirred at room temperature for 1 h. It was then concentrated under reduced pressure to afford crude 230e (1.45 g, 97%), which was used in the next step without further purification. MS: [M+H]+ 381.2.
