Procedure

To a solution of 7-methoxy-4-(phenylsulfinyl)quinoline (0.232 g, 0.819 mmol) in THF (6 mL) at −78° C. was added phenylmagnesium chloride (2.0 M in THF)(0.819 ml, 1.64 mmol). After 5 min, the solution was warmed to RT for 15 minutes. The solution was then cooled to −78° C. and 4-nitrobenzaldehyde (0.371 g, 2.46 mmol) was added in one portion. After 5 min, the solution was warmed to RT. After 1 hr at RT, the reaction was quenched with saturated NH4Cl. The mixture was diluted with CH2Cl2 and washed with water and brine. The organic fraction was dried with Na2SO4 and concentrated in vacuo. The yellow residue was purified by silica gel chromatography using 20-100% Hexanes:EtOAc to afford (7-methoxyquinolin-4-yl)(4-nitrophenyl)methanol as a white solid. [email protected] min
