Examples
Embodiment 1
[0300] (Example 1) Production of a compound represented by formula (I-1)
[0301] [Chemical 54]
[0302]
[0303] Under a nitrogen atmosphere, add 10.0 g of the compound represented by formula (I-1-1), 0.3 g of copper iodide (I), and 0.5 g of bis(triphenylphosphine)palladium dichloride (II) in a reaction vessel , triethylamine 25mL, tetrahydrofuran 50mL. While stirring at room temperature, a solution obtained by dissolving 9.9 g of the compound represented by the formula (I-1-2) in 50 mL of tetrahydrofuran was added dropwise, and stirred at room temperature for 1 hour. 10% hydrochloric acid was poured into the reaction liquid, and extraction was performed with toluene. The organic layer was washed with brine, and purified by column chromatography (silica gel, toluene) and recrystallization (toluene / hexane), thereby obtaining 9.0 g of the compound represented by the formula (I-1-3).
[0304] Under a nitrogen atmosphere, add 9.0 g of the compound represented by formula (I-...
Embodiment 2
[0306] (Example 2) Production of a compound represented by formula (I-2)
[0307] [Chemical 55]
[0308]
[0309] In Example 1, the compound represented by the formula (I-1-4) was replaced by the compound represented by the formula (I-2-2), except that, the same method was used to produce the compound represented by the formula (I-2). indicated compound.
[0310] MS(EI): m / z=435
Embodiment 3
[0311] (Example 3) Production of the compound represented by formula (I-3)
[0312] [Chemical 56]
[0313]
[0314] In Example 1, the compound represented by the formula (I-1-4) was replaced by the compound represented by the formula (I-3-2), except that, the same method was used to produce the compound represented by the formula (I-3). indicated compound.
[0315] MS(EI): m / z=456
