Reaction Steps

A mixture of (±)-1-(3,3-difluorocyclohexyl)-2,4-bis(methoxymethoxy)benzene (30 mg), methanol (2 ml) and acidic ion exchange resin (200 mg) was heated under reflux for 4 h. The reaction mixture was filtered and the resin was washed with methanol. The combined filtrate and washings were evaporated in vacuo and the crude residue was purified by preparative HPLC to give the title compound as a solid (5 mg, 23%). δH (CD3OD) 1.2-2.2 (8H, m), 3.08 (1H, m), 6.23-6.27 (2H, m), 6.87 (1H, d); m/z (ES−) 287 (M−1+AcOH)−.
