After synthesizing Compound G using Compound E and Compound F, Compound P3 was prepared in the same manner as in Preparation Example 1 except that Compound H was used instead of Compound A and Compound G was used instead of Compound B.
MS [M+H]+ (Compound G)=322
MS [M+H]+ (Compound P3)=586
Compound P4 was prepared in the same manner as in Preparation Example 1 except that Compound I was used instead of Compound A and Compound J was used instead of Compound B.
MS [M+H]+ (Compound P4)=507
Compound P5 was prepared in the same manner as in Preparation Example 1 except that Compound K was used instead of Compound A and Compound L was used instead of Compound B.
MS [M+H]+ (Compound P5)=431
