Participants

Reaction Steps

A suspension of 0.59 g of 4,5-dihydro-10-(hydroxymethyl)-8-phenyl-7H-thieno[2,3-a]quinolizine-7-one in 15 ml of dioxane was treated with 0.38 ml of phenyl chloroformate and 0.27 ml of pyridine and stirred at room temperature for 2.5 hours. Then, 3 ml of morpholine were added and the mixture was stirred further until the reaction was completed. The mixture was diluted with chloroform, washed with 1N hydrochloric acid, 10 percent potassium bicarbonate solution and saturated sodium chloride solution, dried over magnesium sulfate and concentrated. By crystallization from ethanol, there was obtained pure (4,5-dihydro-7-oxo-8-phenyl-7H-thieno[2,3-a]quinolizin-10-yl)methyl 4-morpholine carboxylate of m.p. 163°-164°.
