Reaction Steps

To a DMF solution of (5,8-Dihydro-6H-[1,7]naphthyridin-7-yl)-acetic acid hydrochloride (Preparation 235) (34.2 mg, 0.18 mmol) were added (5-Amino-pyridin-3-yl)-(7-isopropyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-methanone (Preparation 95) (50 mg, 0.18 mmol), HATU (136.4 mg, 0.36 mmol) and Hunig's base (0.092 ml, 0.54 mmol). The mixture was heated at 50° C. for 20 hours and then diluted with ethyl acetate, washed with water, brine, dried over sodium sulphate and evaporated to dryness in vacuo. The crude solid was purified over preparative TLC eluting with 5% MeOH/EtOAc to afford the title compound as off white solid in 26% yield, 21 mg. 1H NMR (400 MHz, DMSO-D6) δ: 1.55 (d, 6H), 2.85-2.92 (m, 4H), 3.45 (s, 2H), 3.80 (s, 2H), 5.10 (m, 1H), 7.19 (dd, 1H), 7.56 (d, 1H), 8.32 (d, 1H), 8.53 (s, 1H), 8.56 (t, 1H), 8.73 (d, 1H), 8.99 (s, 1H), 9.07 (d, 1H), 9.45 (s, 1H), 10.31 (s, 1H); LCMS (system 9): Rt=1.77 min; m/z 456 [M+H]+.
