Reaction Steps

To a solution of methyl 2-(4,6-dichloropyrimidin-5-yl)acetate (1.00 equiv; 65.10 mmol; 14.39 g) in DMF (0.5 M; 1.68 mol; 130.20 mL), add 4-methoxybenzylamine (1.10 equiv; 71.61 mmol; 9.36 mL) and DIPEA (1.20 equiv; 78.12 mmol; 13.62 mL) and stir the mixture at 60° C. for 1 h. Quench with ice-water, extract with EA, and wash the organic layer with 1N HCl, water and brine, dry over MgSO4, filter and concentrate in vacuo to the title compound (54.98 mmol; 17.69 g; 84.45%) as a yellow solid and use without further purification. 1H NMR (300 MHz, DMSO): 8.20 (s, 1H), 7.21-7.18 (m, 2H), 6.89-6.85 (m, 2H), 4.53 (d, J=5.8 Hz, 2H), 3.76 (s, 2H), 3.71 (s, 3H).
