Participants

Reaction Steps

A mixture of 2-[5-methyl-3-(2-(methylsulfonyl)phenylsulfonyloxy)phenoxy]ethoxytoluene (480 mg, 1.01 mmol), as prepared in the preceding step, 10% palladium on activated carbon (48.2 mg, ethanol (2 mL) and tetrahydrofuran (9 mL) was stirred at ambient temperature under hydrogen (balloon) for 45 minutes. The mixture was filtered through Celite and the filtrate was concentrated to give the title compound (404 mg, quantitative) as a colorless gum. 1H-NMR (300 MHz, CDCl3) δ8.45 (dd, 1H, J=7.8, 1.4 Hz), 8.13 (dd, 1H, J=7.8, 1.4 Hz), 7.88 (td, 1H, J=7.7, 1.4 Hz), 7.75 (td, 1H, J=7.7, 1.4 Hz), 6.60-6.66 (m, 3H), 3.77-3.98 (m, 4H), 2.25 (s, 3H), 1.95 (t, 1H, J=6 Hz). Mass spectrum (MALDI-TOF, α-cyano-4-hydroxycinnamic acid matrix) calcd. for C16H18O7S2: 409.0 (M+Na). Found: 408.7.
