Reaction Steps

A mixture of 4-chloro-N-(2-methoxyethyl)-6-methyl-1,3,5-triazin-2-amine (300 mg, 1.480 mmol), 5-chloro-2-fluoropyridin-3-ylboronic acid (320 mg, 1.825 mmol), potassium acetate (298 mg, 3.04 mmol), and Am-phos PdCl2 (47 mg, 0.066 mmol) in dioxane (10 mL) was heated at 100° C. under nitrogen. After 6 h, the mixture was cooled to rt and partitioned between water (10 mL) and EtOAc (20 mL). The organic layer was dried over Na2SO4 and concentrated. The oil was purified on silica using EtOAc in hexane (10-80%) to give the product as a yellow solid (130 mg). LCMS (ES, pos.): calcd for C12H13ClFN5O: 297.1. found: 298.1 (M+H)+. 1H NMR (400 MHz, CDCl3) δ 8.55 (ddd, J=16.24, 7.92, 2.64 Hz, 1H); 8.27 (br s., 1H); 5.91 (br. s., 1H); 3.72 (quin, J=5.62 Hz, 2H); 3.59 (t, J=5.09 Hz, 2H); 3.40 (2s, 3H); 2.51 (2s, 3H).
