Reaction Steps

To a suspension of 2,4-dichlorophenylacetic acid methyl ester (1.38 mmol) and paraformaldehyde (1.45 mmol) in 2.7 mL DMSO was added NaHCO3 (0.07 mmol). The reaction mixture was stirred at RT for 2 h and then quenched with water. The mixture was neutralized with 1M HCl solution and extracted with EtOAc (2×). The combined organic layers were dried over MgSO4 and concentrated in vacuo. Purification by CC (KP-SIL™ from Biotage) using Hept to Hept/EtOAc (1/1) gives the desired compound as colorless oil;
