Reaction Steps
Example 15 was repeated except for using 12.76 g (110 mmoles) of 1,3-dimethyl-2-methylene-1,3-propanediol and 8.62 g (50 mmoles) of 4-chloro-o-xylylene glycol, instead of 9.69 g (110 mmoles) of 2-methylene-1,3-propanediol and 6.91 g (50 mmoles) of o-xylylene glycol respectively, to obtain 8.34 g of spiro[7-chloro-1,5-dihydro-2,4-benzodioxepin-4'6'-dimethyl-5'-methylene-3,2'-[1,3]dioxane].
