To a stirred suspension of methyl 1-((2-hydroxyphenyl)carbamoyl)cyclopropanecarboxylate (0.147 g, 0.62 mmol) in 2.5 mL THF at room temperature under nitrogen was added triphenylphosphine (0.361 g, 1.375 mmol) followed by DIAD (0.2663 ml, 1.375 mmol). After 2 hours, the reaction mixture was loaded directly onto a Biotage 40S column in THF and was eluted with 9/1 hexanes/EtOAc to provide the desired product as a yellow oil (132 mg, 97%).
