실험 절차

To a solution of ethyl 2-fluoronicotinate (0.15 g, 0.97 mmol) in NMP (0.5 mL) was added diisopropylethyl amine (0.50 mL, 2.9 mmol), and 8-oxa-3-azabicyclo[3.2.1]octane (0.17 g, 0.72 mmol). The resulting mixture was irradiated with microwaves (100° C.) for 1 h and loaded directly onto a silica column. Eluting the column with EtOAc/hexanes (0-100%) provided methyl 2-(8-oxa-3-azabicyclo[3.2.1]octan-3-yl)nicotinate as a clear oil (0.100 g, 42% yield). MS (ES) for C13H16N2O3: 249 (MH+).
