To a solution of N-(4-cyano-2-hydroxymethyl-benzyl)-2-nitro-N-(5,6,7,8-tetrahydro-quinolin-8-yl)-benzenesulfonamide (2.32 g, 4.85 mmol) dissolved in DMF (50 mL) was added K2CO3 (3.35 g, 24.3 mmol) and thiophenol (1.49 mL, 14.6 mmol). The solution was stirred at room temperature under a positive pressure of N2 for 3 hours. The mixture was concentrated in vacuo and redissolved in CH2Cl2 (50 mL). The mixture was filtered through a sintered glass funnel containing celite. The solution was concentrated in vacuo to afford a yellow solid. Purification via column chromatography on silica gel (hexane:EtOAc, 1:1, v/v) afforded 3-hydroxymethyl-4-[(1,2,3,4-tetrahydro-naphthalen-1-ylamino)-methyl]-benzonitrile as a yellow solid (1.22 g, 86%). 1H NMR (CDCl3) δ 1.92 (m, 3H), 2.26 (m, 1H), 2.77 (m, 2H), 3.86 (m, 1H), 4.02 (d, 1H, J=13.3 Hz), 4.17 (d, 1H, J=12.3 Hz), 4.51 (d, 1H. J=12.3 Hz), 4.80 (d, 1H, J=11.4 Hz), 7.09 (dd, 1H, J=8.3, 5.3 Hz), 7.42 (d, 1H, J=6.6 Hz), 7.49 (d, 1H, J=7.9 Hz), 7.59 (m, 1H), 7.64 (s, 1H), 8.35 (d, 1H, J=4.8 Hz).
