The intermediate 2-Fluoro-4-methoxy-3-(1-ethyl-4,4,6-trimethyl-2-oxo-1,2,3,4-tetrahydro-quinolin-7-yl)-benzaldehyde was prepared in a similar manner to example 7a using 7-bromo-1-ethyl-4,4,6-trimethyl-3,4-dihydro-1H-quinoline-2-one (example 2b) and 2-Fluoro-3-iodo-4-methoxy benzaldehyde (example 7b). 59% yield. 1H NMR (300 MHz; CDCl3): 1.21 (t, J=6.9 Hz, 3 H), 1.31 (s, 3 H), 1.34 (s, 3 H), 1.60 (s, 2 H), 2.10 (s, 3 H), 2.52 (s, 2 H), 3.88 (s, 3 H), 4.02 (q, J=7.2 Hz, 1 H), 6.82 (s, 1 H), 6.93 (d, J=9.0 Hz, 1 H), 7.22 (s, 1 H), 7.95 (t, J=8.1 Hz, 1 H), 10.26 (s, 1 H).
