Participants

Reaction Steps

A mixture of 6-chloro-4-(pyridin-3-ylmethylamino)nicotinamide (28.2, 27 mg, 0.1 mmol), N-(5-amino-2-fluorophenyl)pyrrolidine-1-carboxamide (28.5, 34 mg, 0.15 mmol), Pd(OAc)2 (2 mg). BINAP (15 mg), Cs2CO3 (100 mg) in dioxane (1 mL) was heated at 120° C. under microwave for 60 min Purification with reversed phase HPLC, 6-(4-fluoro-3-(pyrrolidine-1-carboxamido)phenylamino)-4-(pyridin-3-ylmethylamino)nicotinamide (28.6, 10 mg) was obtained. MS found for C23H24FN7O2 as (M+H)+ 450.5, UV: λ=249.1 nm. 1H NMR: (CD3OD) δ8.50 (s, 1H), δ8.42 (d, 1H), δ8.26 (d, 1H), δ7.80 (dd, 1H), δ7.60 (dd, 1H), δ7.40 (dd, 1H), δ7.00 (dd, 1H), δ6.91 (m, 1H), δ5.88 (d, 1H), δ4.49 (s, 2H), δ3.48 (m, 4H), δ1.99 (b, 4H).
