Reaction Steps

The title material is prepared in 34% yield by reacting 5-Oxo-6,7,8,9-tetrahydro-5H-benzocycloheptene-2-carboxylic acid (J. Org. Chem. 1962, 27(1), p 70-76) and (4′-Butyl-2-fluoro-biphenyl-3-yl)-hydrazine hydrochloride (prepared as in example 69, steps 1 and 2 except using 4-n-butylphenylboronic acid as the coupling partner) in an analogous manner to example 1, step 3 except that purification is accomplished by reverse phase mass triggered HPLC: 1H NMR (Acetone-d6) δ 10.72 (bs, 1H), 8.09 (d, 1H), 7.99 (d, 1H), 7.92 (s, 1H), 7.58 (d, 2H), 7.45 (d, 1H), 7.31 (d, 2H), 7.17 (dd, 1H), 3.18 (t, 2H), 3.10-3.04 (m, 2H), 2.72 (t, 2H), 2.22-2.14 (m, 2H), 1.73-1.64 (m, 2H), 1.45-1.38 (m, 2H), 0.96 (t, 3H); LC/MS calculated for [M+H]+ C28H26FNO2: 428.2, found: 428.2.
