Reaction Steps

To a 20 mL vial was added 3-(azetidin-3-yl)pyridine, bistrifluoroacetic acid (75 mg, 0.207 mmol) and diisopropylethylamine (0.109 ml, 0.622 mmol) in dichloromethane (2072 μl. Methyl 4-isocyanatobenzoate (47.7 mg, 0.269 mmol) was added, and the mixture was stirred at room temperature for 2 hours and concentrated by rotary evaporation. The residue was purified by regular phase chromatography to give the title compound. 1H NMR (300 MHz, DMSO-d6) δ 8.90 (s, 1H), 8.57 (d, J=2.1 Hz, 1H), 8.48 (dd, J=4.8, 1.6 Hz, 1H), 7.91-7.82 (m, 3H), 7.71-7.64 (m, 2H), 7.41 (ddd, J=7.9, 4.7, 0.8 Hz, 1H), 4.42 (t, J=8.4 Hz, 2H), 4.05-3.96 (m, 2H), 3.89 (dt, J=8.1, 7.0 Hz, 1H), 3.81 (s, 1H); MS (ESI(+)) m/e 312 (M+H).
