Participants

Reaction Steps

A solution of 2-[4-(bromoacetyl)phenoxy]-N-(phenylmethyl)acetamide (1.40 g) (preparation described in EPO 052442) in acetonitrile (5 ml) was added to a stirred solution of 1-(4-pyridyl)piperazine (1.14 g) in acetonitrile (20 ml). After stirring overnight the liquors were decanted from the residual gum, then concentrated in vacuo. Purification by flash chromatography on silica, eluting with 2 to 5% v/v methanol/dichloromethane, gave a solid. Trituration of this solid with diethyl ether gave the title compound, 95 mg: m.p. 150°-151° C.; NMR (d6DMSO) δ8.67(1H,bt) 8.15(2H,d), 8.00(2H,d), 7.26(5H,m), 7.06(2H,d), 6.81(2H,d), 4.66(2H,s), 4.34(2H,d), 3.84(2H,s), 3.33(4H,t), 2.54(4H,t); m/e 445 (M+H)+ ; calculated for C26H28N4O3. 0.25H2O: C, 69.5; H, 6.4; 12.5. found: C, 69.6; H, 6.4; N, 12.3%.
