<p>Provided is a manufacturing method for synthesizing a novel compound represented by general formula (1). (In general formula (1), R1 is a hydrogen atom, hydroxyl group, carboxyl group, C1-C8 alkyl group, C1-C8 alkoxy group, sulfonate group or benzyloxy group. R2 is a hydrogen atom, hydroxyl group, or C1-C4 alkoxy group. R3 is represented by formula (2).) (In general formula (2), R4 is a hydrogen atom or methyl group. R5 is a single bond or a C1-C4 alkylene group that may have a substituent.) Synthesis is by a method that uses compounds described in formula (3) or (4) as a starting material or an intermediate. (In general formula (3), R6 is a single bond or a C1-C4 alkylene group that may have a substituent.) (In general formula (4), R7 is a hydrogen atom or methyl group. R8 is a single bond or a C1-C4 alkylene group that may have a substituent.)</p> |
