実験手順

Ammonium chloride (0.08 g) was added to a solution of 3-(2-hydroxyethyl)benzaldehyde (example 20, step b) (0.45 g) and triethoxymethane (0.55 g) in EtOH (8 mL) and the reaction mixture heated at 70° C. for 3 h. After cooling, the reaction mixture was partitioned between ethyl acetate and saturated sodium bicarbonate solution. The ethyl acetate solution was dried over sodium sulphate, filtered and evaporated in vacuo to give the subtitled compound as a gum. Yield 0.24 g.
