Procedure
The title compound was synthesized from (4-fluoro-phenyl)-propynoic acid methyl ester and 7-[2-(1H-Indol-5-yloxy)-ethyl]-3,4-dihydro-2H-[1,8]naphthyridine-1-carboxylic acid tert-butyl ester using the procedure described in Example 17, step (a), in 73% yield as an E/Z isomeric mixture. 1H NMR (CDCl3) [E/Z mixture] δ 7.43 (m, 1H), 7.30 (m, 2H), 7.00–7.20 (m, 3), 6.94 (m, 1H), 6.50–6.90 (m, 3H), 6.12 (s, 1H), 4.36 (m, 2H), 3.75 (m, 2H), 3.7 and 3.6 (s, 3H), 3.20 (m, 2H), 2.75 (m, 2H), 1.90 (m, 2H), 1.50 (s, 9H). Mass Spectrum (LCMS, ESI) calculated for C33H35FN3O5 572.3 (M+H); found 472.3 (M-Boc+H).
