(R)-tert-Butyl (2-oxopyrrolidin-3-yl)carbamate → [1-(1-Chloroisoquinolin-7-ylmethyl)-2-oxopyrrolidin-3-(R)-yl]carbamic acid tert-butyl ester
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | (R)-tert-Butyl (2-oxopyrrolidin-3-yl)carbamate | HCID 10774403 | — |
| Reactant | 7-(Bromomethyl)-1-chloroisoquinoline | HCID 18176252 | — |
| Product | [1-(1-Chloroisoquinolin-7-ylmethyl)-2-oxopyrrolidin-3-(R)-yl]carbamic acid tert-butyl ester | HCID 86757283 | 80.1% |
Reaction Steps
Same procedure as EXAMPLE 101D, but using (2-oxopyrrolidin-3-(R)-yl)carbamic acid tert-butyl ester (312 mg, 1.56 mmol) and 7-bromomethyl-1-chloroisoquinoline (440 mg, 1.72 mmol) as the starting materials. The crude product is purified by column chromatography on silica with 50-100% ethyl acetate/hexanes. The product fractions are combined and concentrated to give the product as a pale yellow powder (471 mg. 1.25 mmol).
