Procedure

Example 1 was repeated except for using 10.53 g (76 mmoles) of 2-methyl-4-chloro-1,3-butanediol and 6.00 g (35 mmoles) of 4-chloro-o-xylylene glycol, instead of 9.48 g (76 mmoles of 4-chloro-1,3-butanediol and 4.76 g (35 mmoles) of o-xylylene glycol, respectively, to obtain spiro[7-chloro-1,5-dihydro-2,4-benzodioxepin-4'-methylene-5'-methyl-3,2'-[1,3dioxane.
