Reaction Conditions

Temperature	30 °C

Reaction Steps

A mixture of 4-methoxyaniline (5.00 g, 40.6 mmol), chloroacetic acid (8.6 g, 91.5 mmol), EDCI (12.0 g, 61.2 mmol), HOBT (8.4 g, 61.3 mmol) and NMM (13 mL, 122 mmol) in anhydrous CH2Cl2 (50 mL) was stirred at 30° C. for 3 hours. The mixture was quenched with ice water, and then extracted with CH2Cl2 (30 mL×2). The combined organic layers were washed with brine (30 mL), dried over Na2SO4, filtered and concentrated to give the crude product, which was purified by silica gel column (PE/EtOAc=5/1) to give the product (1.60 g, yield 20%).
