Reaction Steps

A solution of impure 4-bromomethyl-5-butyl-2-chloro-6-phenyl-pyrimidine (288 mg) and 4-{[(2,3-dihydro-benzo[1,4]dioxin-6-ylmethyl)-amino]-methyl}-benzoic acid methyl ester (190 mg, 0.606 mmol) in CH3CN containing K2CO3 (300 mg) is stirred at room temperature. The reaction is monitored by TLC until complete consumption of 4-bromomethyl-5-butyl-2-chloro-6-phenyl-pyrimidine (24 hours). The mixture is then diluted with CH2Cl2 and filtered. The filtrate is concentrated, and the resulting residue is purified by flash chromatography on silica gel. Elution with 5:1 hexanes-EtOAc followed by 4:1 hexanes-EtOAc affords 215 mg of pure 4-{[(5-butyl-2-chloro-6-phenyl-pyrimidin-4-ylmethyl)-(2,3-dihydro-benzo[1,4]dioxin-6-ylmethyl)-amino]-methyl}-benzoic acid methyl ester. 1H NMR (CDCl3, 300 MHz) δ 7.97 (d, J=8.1 Hz, 2H), 7.44–7.33 (m, 7H), 6.84 (s, 1H), 6.79 (s, 2H), 4.22 (s, 4H), 3.90 (s, 3H), 3.74 (s, 2H), 3.72 (s, 2H), 3.55 (s, 2H), 2.64–2.56 (m, 2H), 1.01 (m, 2H), 0.90 (sext, J=7.2 Hz, 2H), 0.61 (t, J=7.2 Hz, 3H) ppm. MS: m/z 572 [M+1].
