Vorschrift

A mixture of 4-[7-(6-oxa-3-azabicyclo[3.1.1]heptan-3-yl)quinoxalin-5-yl]oxycyclohexanamine (190 mg, 0.5581 mmol), 2-fluoropyrimidine (60 mg, 0.6118 mmol) and DIEA (200 μL, 1.148 mmol) in 2-propanol (2 mL) was heated in a microwave reactor for 20 min at 150° C. The reaction mixture was concentrated, and then purified from 12 g silica gel cartridge with 0-6% MeOH/DCM to yield N-[4-[7-(6-oxa-3-azabicyclo[3.1.1]heptan-3-yl)quinoxalin-5-yl]oxycyclohexyl]pyrimidin-2-amine (120.2 mg, 48.9%) as a yellow solid. Mass+1: 419.23; Retention Time: 0.72; NMR Annotation: 1H NMR (400 MHz, Chloroform-d) δ 8.42 (d, J=1.9 Hz, 1H), 8.30 (d, J=1.9 Hz, 1H), 8.04 (d, J=4.8 Hz, 2H), 6.65-6.56 (m, 2H), 6.28 (t, J=4.8 Hz, 1H), 4.99 (d, J=8.1 Hz, 1H), 4.60 (d, J=6.5 Hz, 3H), 3.79 (dd, J=8.2, 4.0 Hz, 0H), 3.62-3.38 (m, 4H), 3.17-3.03 (m, 1H), 2.07-1.90 (m, 2H), 1.89-1.59 (m, 7H).
