A solution of 7-[(1S)-1-aminoethyl]-6-(3-fluorophenyl)-3-methyl-5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one (50 mg, 0.16 mmol), 7-chloro-3H-imidazo[4,5-b]pyridine (51 mg, 0.33 mmol), and N,N-diisopropylethylamine (57 μL, 0.33 mmol) in 1-butanol (0.5 mL) in a sealable vial was degassed with nitrogen, sealed, and heated at 140° C. for 48 hours. The reaction mixture was diluted with methanol and purified by RP-HPLC (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.1% ammonium hydroxide, at flow rate of 60 mL/min) to give the desired product (7 mg, 10%) as a white solid. LCMS for C21H18FN6OS (M+H)+: m/z=420.8. 1H NMR (400 MHz, CD3OD): δ 8.04 (s, 1H), 7.83 (d, J=5.9 Hz, 1H), 7.55-7.49 (m, 1H), 7.23-7.12 (m, 3H), 6.86 (d, J=1.2 Hz, 1H), 5.96 (d, J=5.9 Hz, 1H), 4.69-4.67 (m, 1H), 2.75 (s, 3H), 1.57 (d, J=6.4 Hz, 3H).
