Reaction Steps

A solution of 6-fluoro-3,4-dihydro-2H-naphthalen-1-one (3.64 kg) and 3-fluorothiophenol (2.80 kg), in anhydrous NMP (7.7 kg) was treated with triethylamine (2.26 kg). After a mild exotherm had subsided, the mixture was heated for 20 hours at 90° C. The mixture was cooled to about 25° C. and diluted with water (30 L) and heptane (10 kg). The mixture was agitated for 12 hours and then filtered. The filter cake was washed with water and dried at 60° C. under vacuum to afford 6-(3-fluorophenylsulfanyl)-3,4-dihydro-2H-naphthalen-1-one (5.52 kg): MP=66.2-66.7° C.; MS (M+1)=273; H1 NMR (300 MHz): δ ppm (CDCl3): 2.10 (2H, m, J=6.03, 6.40 Hz), 2.62 (2H, dd, J=6.03, 5.75 Hz) 2.87 (2H, t, J=6.03), 7.03 (1H, tdd, J=1.13, 2.64, 8.29 Hz), 7.08-7.16 (2H, m), 7.22 (1H, dt, J=1.13, 8.29 Hz), 7.31 (1H, q, 8.29 Hz), 7.35 (1H, dd, J=5.65, 7.91 Hz) 7.92 (1H, d, J=7.91 Hz).
