Reaction Steps

A mixture of 3-bromo-6-(4-cyclopropyl-[1,4]diazepane-1-carbonyl)-pyridine-2-carbonitrile (0.600 g, 1.71 mmol), 3-hydroxytetrahydrofuran (301 mg, 3.41 mmol), and anhydrous Cs2CO3 (1.67 g, 5.13 mmol) in DMSO (7 mL) was heated by microwave irradiation at 150° C. for 35 min. The mixture was diluted with water and extracted with Et2O. The combined organic layers were dried (Na2CO3) and concentrated. The residue was purified by FCC to give the title compound (280 mg, 46%). MS (ESI): mass calcd. for C19H24N4O3, 356.4; m/z found, 357.5 [M+H]+. 1H NMR (CDCl3): 7.94 (d, J=8.8 Hz, 1H), 7.35 (d, J=8.9 Hz, 1H), 5.08-5.04 (m, 1H), 4.12-3.93 (m, 4H), 3.77-3.72 (m, 2H), 3.69-3.63 (m, 2H), 2.98-2.92 (m, 2H), 2.87-2.81 (m, 2H), 2.35-2.25 (m, 1H), 2.25-2.18 (m, 1H), 1.97-1.83 (m, 3H), 0.51-0.35 (m, 4H).
