To a stirring suspension of 6-chloro-2-oxo-4-phenyl-1,2-dihydro-quinoline-3-carboxylic acid chloride (29 mg, 0.09 mmol) in DCM (0.5 mL) was added (S)-(+)-leucinol (30 μL, 0.23 mmol). Within 5 min, the mixture became homogeneous and the reaction was complete as determined by LCMS. Chloroform (2 mL) was added, and the solution was extracted with IN HCl (4×1 mL) and water (2×1 mL). The chloroform layer was purified directly by flash chromatography eluting with chloroform, then chloroform/methanol (100:1)->(50:1)->(25:1) to afford 6-chloro-2-oxo-4-phenyl-1,2-dihydro-quinoline-3-carboxylic acid (1-hydroxymethyl-3-methylbutyl)amide (b) (19 mg, 52%) as a white powder. MS: 399.2 (M+H).
