Reaction Steps

A mixture of 4-[4-chloro-6-(2,6-diethyl-phenyl)-2-methyl-pyridin-3-ylmethyl]-2,2-dimethyl-morpholine (30 mg, 0.08 mmol), 2,4-dihydroxy-benzamide (24 mg, 0.16 mmol), copper powder (10 mg) and K2CO3 (22 mg, 0.16 mmol) in 1-methyl-2-pyrrolidinone (1 mL) is heated at 150° C. overnight. After cooling, EtOAc (10 mL) and water (10 mL) are added to the mixture. The organic layer is separated, washed with brine (3×), dried (Na2SO4) and concentrated. The crude is purified by PTLC (1:1 Hexane/EtOAc) to give to give the title compound. 1H NMR (CDCl3) 12.41 (s, 1H), 7.35 (d, 2H), 7.23 (m, 1H), 7.10 (m, 2H), 6.63 (s, 1H), 6.51 (m, 2H), 5.85 (br, 2H), 3.72 (m, 2H), 3.56 (s, 2H), 2.74 (s, 3H), 2.41-2.30 (m, 6H), 1.20 (s, 6H), 1.76 (m, 2H), 1.01 (t, 6H).
