Procedure
Following a procedure analagous to that of Example 1(b) but using respectively 2,6-diethoxy-3-(α-ethoxy-2-chlorobenzyl)tetrahydropyran and 2,6-diethoxy-3-(α-ethoxy-4-methoxybenzyl)tetrahydropyran there was obtained respectively 2-(2-chlorobenzylidene)glutaraldehyde, b.p. 155° C. (0.8 mm), yield: 57%; and 2-(4-methoxybenzylidene)glutaraldehyde, b.p. 175° C. (1.0 mm), yield 61%.
