Reaction Steps
28.32 g. (0.1 mole) 7-(2'-bromo-ethyl-oxy)-4-methyl-coumarin and 33.23 g. (0.2 mole) triethylphosphite are heated under stirring for 1 hour. The reaction mixture is then cooled. The end-product is separated from the contaminations by removing same by vacuum distillation. The bottom product is a yellow, thick, oily substance of weight 11.9 g. (0.0035 mole), nD31 =1.5619.
