Procedure

To a solution of 319 mg (0.596 mmol) of 2-chlorobenzenesulfonic acid 1-[[1-N-(tert-butoxycarbonyl)piperidin-4-yl]methoxy]naphthalen-3-yl ester, as prepared in the preceding step, in 2 mL of methylene chloride was added 1.5 mL (6 mmol) of 4 N HCl in dioxane. The reaction mixture was stirred for 1 h and triturated with diethyl ether to afford 281 mg of the title compound as a colorless powder. 1H-NMR (300 MHz, DMSO-d6) δ 8.94 (bd, 1 H, J=9 Hz), 8.68 (bd, 1 H, J=10 Hz), 8.6 (d, 1 H, J=8 Hz), 7.8-7.98 (m, 4 Hz), 7.50-7.6 (m, 3 H), 7.18 (d, 1 H, J=2 Hz), 6.69 (d, 1 H, J=2 H), 3.94 (d, 2 H, J=7 Hz), 2.93 (q, 2 H), 2.16 (bm, 1 H), 1.96 (d, 2 H), and 1.57-1.71 (m, 2 H). Mass spectrum (MALDI-TOF; gentisic acid matrix) calcd. for C22H22ClNO4S: 432.1 (M+H). Found: 431.5.
