Reaction Steps

(1R,6S)-3,8-Diazabicyclo[4.2.0]octan-8-yl(2-fluoro-6-(2H-1,2,3-triazol-2-yl)phenyl)methanone (Intermediate 29, 56 mg, 0.19 mmol), 2-chloro-4,6-dimethylpyrimidine (32 mg, 0.22 mmol) and DIPEA (96 μL, 0.56 mmol) in ACN (2 mL) were heated in a microwave reactor for 1 h at 150° C. Then the reaction mixture was diluted with water and extracted with DCM (2×). The combined organics were dried (Na2SO4) and concentrated. Purification via prep HPLC (Agilent, basic) gave 40 mg (53%) of the title compound as a clear oil. MS (ESI) mass calcd. For C21H22FN7O, 407.45; m/z found 408.0 [M+H]+. 1H NMR (CDCl3): 8.00-6.88 (m, 5H), 6.38-5.88 (m, 1H), 4.95-3.57 (m, 6H), 3.29-2.61 (m, 2H), 2.47-1.80 (m, 8H).
