実験手順

Using a similar procedure to that of Preparation VI-3, but using 1.3 equivalents of 4-fluorophenylboronic acid to 1 equivalent of (R,R)—N-[3,4-dibromoisothiazol-5-yl]-2-methylcyclopropanecarboxamide and stirring the reaction mixture at 70° C. for 1 day affords (R,R)—N-[4-bromo-3-(4-fluorophenyl)isothiazol-5-yl]-2-methylcyclopropane-carboxamide. ES-MS: m/e 357.0 (m+1).
