Embodiment 1
[0508] Intermediate Example 1: 5-(Chlorosulfonyl)-2-methoxyphenyl methanesulfonate
[0509] a). Preparation of 2-methoxyphenyl methanesulfonate: Triethylamine ( 8.5 mL, 61.04 mmol) and methanesulfonyl chloride (4.72 mL, 61.04 mmol). After stirring for 2 h, the reaction was complete as shown by TLC. The reaction solution was diluted with saturated ammonium chloride and water, the organic phase was separated and concentrated in vacuo to an oil. The crude material was purified by silica gel chromatography eluting with ethyl acetate / hexanes. The desired product was obtained as a clear oil (7.5 g, 91% yield). 1 HNMR (DMSO-d6, 400MHz) δ: 7.31 (1H, dq), 7.28 (1H, dd), 7.19 (1H, dd), 6.97 (1H, dq), 3.82 (s, 3H), 3.32 (3H, s ).
[0510] b). Preparation of 5-(chlorosulfonyl)-2-methoxyphenyl methanesulfonate: To cooled (-10°C) chlorosulfonic acid (1 1.78mL, 176.5mmol) and 100mL DCM solution A solution of 2-methoxyphenyl methanesulfonate (7.13 g, 35.3 mmol) dissolved in 15 mL of DCM...
Embodiment 2
[0514] Example 2: 1-{[3,4-di(methoxy)phenyl]sulfonyl}-4-{[4-(1,3-oxazol-5-yl)phenyl]sulfonyl}piper Zinc
[0515] This compound was prepared as described in Example 1 except that 3-fluoro-4-(methoxy)benzenesulfonyl chloride was replaced by 4-(1,3-oxazol-5-yl)benzenesulfonyl chloride.
Embodiment 3
[0516] Example 3: 1-{[3,4-bis(methoxy)phenyl]sulfonyl}-4-{[4-methyl-2-(methoxy)phenyl]sulfonyl}piperazine
[0517] This compound was prepared as described in Example 1, except that 3-fluoro-4-(methoxy)benzenesulfonyl chloride was replaced by 4-methyl-2-(methoxy)benzenesulfonyl chloride.
