Reaction Conditions

Reaction Steps

In a reactor bottle (trimethylsilyl)diazomethane, 2.0 M in diethyl ether (2.4 mL, 4.8 mmol) was added to a mixture of 2-(4-(1,3-dioxan-2-yl)-2-fluorophenyl)-6-(1-phenylvinyl)-benzo[d]thiazole (0.650 g, 1.6 mmol), in anhydrous dioxane 15.00 mL. The reaction mixture was heated to 150° C. for 18 h. At which time the crude reaction mixture was concentrate in vacuo and purified by silica gel chromatography to afford as a mixture of isomers 2-(4-(1,3-dioxan-2-yl)-2-fluorophenyl)-6-(1-phenyl-2 (trimethylsilyl)cyclopropyl)benzo[d]thiazole. MS (ESI) m/z: Calculated: 503.2; Observed: 504.0 (M++1).
