Reaction Steps

A solution of 4.0 g of N,N-dipropyl-5,6-dihydro-4H-thieno[2,3-b]thiopyran-5-amine in 20 ml of t-butyl methyl ether is slowly added while stirring to a mixture of 5.42 g of 2.4 M ethanolic hydrogen chloride in 45 ml of t-butyl methyl ether. The crystalline product is collected, washed with the solvent and dried to give N,N-dipropyl-5,6-dihydro-4H-thieno[2,3-b]thiopyran-5-amine hydrochloride, m.p. 163°-167°.
