As in Example 8, 45.6 g. (0.17 mol) of 8-methoxy-4-hydroxy-3-phenyl-coumarin are treated with 30.5 g. (0.20 mol) of 2-morpholino-1-chlorethane. After evaporation of the chloroform and recrystallisation from isopropanol, 48 g. of a beige-coloured solid are obtained. M.P. 90°-91° C.; yield 76% (theoretical yield 63 g.).
