Procedure

To an ice cold solution of 1.46 g (7.40 mmol) of 4-((2S)-2-methoxymethylpyrrolidin-1-yl)but-2-ynoic acid in 85 mL of THF under N2 was added 0.897 g (8.88 mmol) of N-methylmorpholine and 0.811 g (5.92 mmol) of isobutyl chloroformate. After stirring in the cold for 30 min, a solution of 1.00 g (2.96 mmol) of 6-amino-4-[(3-bromophenyl)amino]-quinoline-3-carbonitrile in 8 mL of pyridine was added dropwise. The reaction was slowly warmed to 25° C. over 3 h. The reaction was poured into ice water, satd NaHCO3 was added and the product was extracted with ethyl acetate. After drying and solvent evaporation, the residue was chromatographed on silica gel (10% methanol in ethyl acetate). The yield was 0.560 g of 4-((2S)-2-methoxymethylpyrrolidinyl-1-yl)but-2-ynoic acid [4-(3-bromophenylamino)-3-cyanoquinolin-6-yl]amide as a brown foam: mass spectrum (electrospray, m/e): M+H 518.0, 520.0.
