Reaction Conditions

Reaction Steps

The solution of tert-butyl N-{2-[(3-amino-2-chloroquinolin-4-yl)amino]-1,1-dimethylethyl}carbamate in acetonitrile from Part C was cooled to 5° C. using an ice bath. A solution of acetoxyacetyl chloride (4.8 g, 35.1 mmol) in acetonitrile (20 mL) was added dropwise at a rate such that the temperature of the reaction mixture was maintained at 5° C. After the addition was complete the ice bath was removed and the reaction mixture was allowed to stir at ambient temperature for 5 hours. The reaction mixture was concentrated under reduced pressure to provide 16.7 g of N-{2-[(3-acetoxyacetylamino-2-chloroquinolin-4-yl)amino]-1,1-dimethylethyl}carbamate hydrochloride as a yellow powder.
