Dess-Martin periodinane (0.268 g, 0.632 mmol) was added to a solution of 4-(1-hydroxynon-1-yl)benzaldehyde (0.125 g, 0.505 mmol) from Step A in CH2Cl2 (3.0 ml). After 1 h, the reaction was filtered and concentrated. Silica gel chromatography eluting with 19:1 v/v hexane/EtOAc gave 0.107 g (0.446 mmol, 88%) of the title compound: 1H NMR (500 MHz) δ 10.1 (s, 1H), 8.10 (d, J=8.2, 2H), 7.97 (d, J=8.2, 2H), 3.00 (t, J=7.3, 2H), 1.70-1.8 (m, 2H), 1.22-1.42 (m, 10H), 0.88 (t, J=7.0, 3H).
