Procedure

tert-Butyl 4-{4-[1-(tert-butoxycarbonyl)cyclopropyl]phenyl}piperazine-1-carboxylate (16.0 mg, 0.0000397 mol) was treated with hydrogen chloride in 1,4-dioxane (4.0 M, 0.20 mL) at rt for 30 min. The solvent was evaporated under reduced pressure, and the residue was dissolved in acetonitrile (1.0 mL, 0.019 mol) and was treated with N,N-diisopropylethylamine (20.0 μL, 0.000115 mol) and methyl chloroformate (5.0 μL μL, 0.000065 mol). After 30 min, the solvent was evaporated under reduced pressure and the residue was the desired product, which was directly used in the next step without further purification. LC/MS: 361.2 (M+H+).
