실험 절차
Methyl 4-(benzyloxy)-2-fluorobenzoate (52.4 mg) which can be prepared according to the method described in Reference example 30, etc. was dissolved in n-butanol (1 mL; manufactured by Kanto Chemical Co., Inc.), added with hydrazine monohydrate (96 μL; manufactured by Sigma-Aldrich Co.), and stirred in a sealed tube under microwave for 1 hour at 160° C. Precipitates from the reaction solution were filtered and washed with n-butanol to obtain the title compound (39.6 mg).
