## Comparative Synthesis Example 1-1 

Dial 5 was synthesized by the same procedure as Synthesis Example 1-1-2 aside from using Hydroxy-ester Sa instead of Hydroxy-ester la. Amount 43.3 g, yield 81 %. 

b.p.: 59° C./23 Pa 

Hydroxy-ester Sb was synthesized by the same procedure as Synthesis Example 1-1-3 aside from usingDiol 5 instead of $_{40 }$ Dial 1. Amount 63.1 g, yield 93%.
