Sodium hydride → HCID 178424291, compound

Participants

Reaction Steps

To a solution of 400 mg of 6-(4-aminobenzoyl)-1,4,5,6-tetrahydropyrazolo[3,4-d]thieno[3,2-b]azepine in 12.0 ml of dioxane under argon is added 65 mg of sodium hydride (60% in mineral oil). After stirring for 15 minutes, 176 μl of o-toluoyl chloride is added. The reaction mixture is stirred at room temperature for 18 hours under argon. The reaction mixture is evaporated in vacuo to a residue which is dissolved in 40 ml of methylene chloride and washed with 20 ml each of water and brine. The organic layer is dried (Na2SO4) and filtered. The filtrate is concentrated in vacuo to give a residue which is purified by chromatography on silica gel plates by elution with 1:1 ethyl acetate:hexane 100 mg of N-[4-[[4,5-dihydro-2-(2-methylbenzoyl)pyrazolo[4,3-d]thieno[3,2-b]azepin-6(2H)-yl]carbonyl]phenyl-2-methylbenzamide as a white foam and 200 mg of the product as a white foam.
