| Role | Name | HCID | Charge |
|---|
| Reactant | 1,1-Dimethoxyethyl(dimethyl)amine | HCID 87835 | — |
| Reactant | Methyl 4-carbamoyl-2-chlorobenzoate | HCID 53785786 | — |

Reaction Steps
A mixture of 2-chloro-terephthalamic acid methyl ester of Step A (1.02 g, 4.8 mmol) and N,N-dimethylacetamide dimethyl acetal (3.5 mL, 23.9 mmol) was heated at 90° C. for 30 minutes under nitrogen. The solution was cooled, and excess reagent was removed under high vacuum to provide a brown oil which was used as such in the next step.
