Oxalyl chloride → HCID 47364487, compound

Participants

Reaction Steps

To a 100 mL round bottom flask containing 3-bromo-4-methoxybenzoic acid (500 mg, 2.16 mmol) and DCM (5 mL) was added oxalyl chloride (0.23 mL, 2.60 mmol) and DMF (0.1 mL, 0.13 mmol). The reaction mixture was stirred at RT for one hour and concentrated in vacuo. The resulting colorless oil was taken up in DCM (2.5 mL) and added to a mixture of (1-methyl-1H-pyrazol-4-yl)methanamine (241 mg, 2.16 mmol), TEA (0.60 mL, 4.33 mmol) and DCM (2.5 mL) at 0° C. The reaction mixture was stirred at RT for 0.5 hours then concentrated in vacuo. The crude material was purified by silica gel chromatography (0-10% MeOH in DCM) to afford 3-bromo-4-methoxy-N-((1-methyl-1H-pyrazol-4-yl)methyl)benzamide (702 mg) MS [M+H+]=325.9.
