4-Methoxybenzylamine → HCID 73213652, compound

Temperature

0 °C

To a stirred solution of (4-methoxyphenyl)methanamine (0.437 g, 3.18 mmol) in CH2Cl2 (25 mL) was added DIEA (0.556 mL, 3.18 mmol) and the reaction mixture was stirred at 0° C. for 15 min. 4-(4-chloro-2-fluoro-3-methoxyphenyl)-2-methylnicotinoyl chloride (1 g, 3.18 mmol) (prepared by treatment of carboxylic acid with thionyl chloride) dissolved in 10 mL of DCM was then added to the reaction mixture and the reaction was stirred at rt for 10 h. The reaction was quenched by addition of water (50 mL) and the solution was extracted with DCM (2×50 mL). The combined organic layers were washed with brine solution 50 mL, dried over sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by silica gel chromatography using ethyl acetate in hexanes as eluant to yield 4-(4-chloro-2-fluoro-3-methoxyphenyl)-N-(4-methoxybenzyl)-2-methylnicotinamide (800 mg, 1.109 mmol, 35% yield) as a brown oil. LC/MS (ESI) m/e 415.1 [(M+H)+, calcd for C22H21ClFN2O3 415.1]; LC/MS retention time (method D): tR=0.78 min.
