Reaction Steps

A solution of (2-methyl-furan-3-yl)-acetic acid ethyl ester (11.8 g, 70.2 mmoles) in tetrahydrofuran (50 ml) was added to a stirred suspension of lithium aluminium hydride (2.66 g, 70.2 mmoles) under a nitrogen atmosphere and with cooling to 0° C. When the addition was complete the mixture was stirred at room temperature for 3 hours, then quenched by the addition of excess acetone. After acidifying with 10% aqueous hydrochloric acid the mixture was extracted three times with diethyl ether. The combined extracts were dried and evaporated to afford crude 2-(2-methyl-furan-3-yl)-ethanol as a yellow oil. (ii) Compound (70) was prepared in the form of a pale yellow oil from crude 2-(2-methyl-furan-3-yl)-ethanol (from (i)) by adapting the procedure of Example 1(a).
