Reaction Steps

To a solution of 4,6-dichloropyrimidine (660.04 mg, 4.43 mmol) in 1-butanol (10 mL) was added DIPEA (0.67 ml, 4.03 mmol) followed by 2-methoxypyridin-3-amine (500 mg, 4.03 mmol). The reaction mixture was then heated to 90° C. for 2 hr. The reaction mixture was then concentrated in vacuo and partitioned between DCM and water. A precipitate was removed by filtration and the organics extracted (2×20 ml DCM). The combined organic extracts were then washed with 0.5M HCl (5 ml) and then dried (Na2SO4), filtered and concentrated in vacuo to give the title intermediate (300 mg, LC-MS purity=83%); LC-MS: m/z=+236.95/238.90 (M+H)+.
