Participants

Reaction Steps

A mixture of 4-bromomethyl-5-butyl-6-phenyl-pyrimidine (86 mg), (2,3-dihydro-benzo[1,4]dioxin-6-ylmethyl)-(3-ethoxy-benzyl)-amine (93 mg, 0.310 mmol), and K2CO3 (195 mg, 1.4 mmol) in CH3CN (2.0 mL) is stirred at reflux for 1 h and at room temperature for 16 hours. The reaction mixture is then diluted with CH2Cl2 and filtered. The filtrate is concentrated, and the residue purified by preparative TLC, developing with 2:1 hexanes-EtOAc (+0.5% Et3N). The band containing product affords pure (5-butyl-6-phenyl-pyrimidin-4-ylmethyl)-(2,3-dihydro-benzo[1,4]dioxin-6-ylmethyl)-(3-ethoxy-benzyl)-amine. 1H NMR (CDCl3, 300 MHz) δ 8.98 (s, 1H), 7.42 (m, 5H), 7.19 (t, J=8.0 Hz, 1H), 6.92–6.73 (m, 6H), 4.22 (s, 4H), 4.01 (q, J=6.9 Hz, 2H), 3.76 (s, 2H), 3.60 (s, 2H), 3.54 (s, 2H), 2.70–2.64 (m, 2H), 1.41 (t, J=6.9 Hz, 3H), 1.09–0.99 (m, 2H), 0.91 (sext, J=7.2 Hz, 2H), 0.61 (t, J=7.2 Hz, 3H) ppm. MS: m/z 524 [M+1].
