Sodium hydride → HCID 68304566, compound

Participants

Reaction Steps

tert-butyl 5-((diethoxyphosphoryl)methyl)pyrazin-2-ylcarbamate (35 mg, 0.10 mmol) in dried DMF (0.5 mL) was added NaH (5 mg, 0.12 mmol) at 0° C. After 20 minutes, a solution N-(3-formyl-4-methylphenyl)-4-((4-methylpiperazin-1-yl)methyl)-3-(trifluoromethyl)benzamide (44 mg, 0.10 mmol) in dried DMF (0.5 mL) was added slowly into the reaction mixture. The reaction mixture was stirred overnight at room temperature and quenched by adding water. The reaction mixture was partitioned between ethyl acetate and water. The organic layer was separated and the aqueous layer was extracted with ethyl acetate. The combined organic extracts were washed with brine, dried over MgSO4, celite filtered and concentrated under reduced pressure. The crude product was purified by flash chromatography using (3% to 7% MeOH/CH2Cl2) as a solvent to afford title compound (40 mg, 64% yield). MS m/z: 611 [M+1].
