Reaction Conditions

Reaction Steps

As shown in Scheme 2, a mixture of intermediate 1 of Scheme 2 (16 mg) and intermediate 3 of Scheme 1 (1-(3-(4-amino-3-methoxyphenylamino)azetidin-1-yl)ethanone, 20 mg) in dioxane (1.0 mL) with catalytic trifluoroacetic acid was stirred overnight at 50° C. The crude was concentrated under reduced pressure and purified using HPLC (TFA modifier) to give the title compound (12 mg) as a TFA salt. 1H-NMR (DMSO-d6, 400 MHz) δ 10.6 (s, 1H), 10.15 (s, 1H), 9.45 (s, 1H), 8.62 (br, 1H), 6.96-7.85 (m, 4H), 6.55 (dd, J=2, 10 Hz, 1H), 6.23 (d, J=10 Hz, 1H), 5.74 (d, J=10 Hz, 1H), 3.15-3.85 (m, 6H), 1.77 (s, 3H); calculated mass for C26H26F3N7O3: 541.2. found: 542.2 (M+H+).
