p-Toluenesulfonic acid → 2-Methoxymethoxy-biphenyl

Participants

Reaction Steps

The procedure as in Example 1: step a was followed using 2-hydroxybiphenyl (1.70 g, 10 mmol), p-toluenesulfonic acid (190 mg, 1.1 mmol), DCM (5 mL), and dimethoxypropane (5 mL). Analogous aqueous workup yielded the title compound (225 mg, 11%) which was used without further purification. 1H-NMR (CDCl3): δ 7.58 (m, 2H), 7.44 (m, 2H), 7.36 (m, 2H), 7.32 (m, 1H), 7.25 (dd, 1H, J=1.2, 8.1 Hz), 7.12 (dt, 1H, J=1.2, 7.4 Hz), 5.14 (s, 2H), 3.42 (s, 3H).
