Reaction Steps

A solution of 1.8 g. of propionyl chloride in 10 ml. of methylene chloride was added to a stirred solution of 0.01 mole of the above-referred amine in 50 ml. of methylene chloride containing 2.0 ml. of pyridine. The resulting clear solution was stirred overnight at room temperature and then washed with water, 5% aqueous hydrochloric acid, water, 10% aqueous sodium bicarbonate and finally with water. The upper organic layer was dried over magnesium sulfate and concentrated in vacuo to give a solid residue. This residue was recrystallized from ethanol to give N-(1-methyl-1H-(1)-benzothieno[3,2-c]pyrazol-3-yl)propanamide, m.p. 88°-89° C.
