Reaction Steps

1.32 g of water and then 3.91 g of 1-chloro-2-(N,N-dimethylamino)ethane hydrochloride and 5 g of (Z)-8-hydroxyimino-3-methylthieno[2,3-d]pyrrolo[1,2-a]pyrrole (Preparation 36) are added to 6.99 g of sodium carbonate in 200 ml of anhydrous acetone. The reaction mixture is heated at reflux for 40 hours, then the acetone is removed and the residue is taken up in 100 ml of water and then extracted with 200 ml of diethyl ether. The ethereal phase is washed with water, decanted off and then dried over magnesium sulfate, and subsequently concentrated to dryness to yield the title product in the form of an oil.
