A mixture of 2-ethyl-5,6,7,8-tetrahydro-4(1H)-quinolone (1.95 g), and potassium carbonate (2.28 g) in NMP (75 ml) was heated at 60° C. for 20 minutes with stirring. Compound E (5.2 g) was added and the reaction mixture was heated at 80° C. for 90 minutes. The mixture was allowed to cool to ambient temperature and water (150 ml) was added. The resultant precipitate was collected by filtration, dried at 60° C., then recrystallised from toluene to give 2-ethyl-4-[(2'-(1-(4-nitrophenyl)-1H-tetrazol-5-yl)biphenyl-4-yl)methoxy]-5,6,7,8-tetrahydroquinoline, as a solid in 60% yield; m.p. 205°-207° C.; NMR (CDCl3):1.30(3H,t), 1.90(4H,m), 2.60-3.00(6H,m), 5.04(2H,m), 6.52(2H,d), 6.60(1H,s), 6.80(2H,d), 7.11(2H,d), 7.40(1H,d), 7.67(2 H,d), 7.92(3H,m).
