Versuchsvorschrift

In a similar manner to that described in Reference example 2(a), a reaction was carried out using diethyl 2-(4-isopropylphenoxy)malonate (21.5 g), which is the product of Reference example 5(a), 4-benzyloxybenzyl chloride (19.7 g) and sodium hydride (55% suspension in oil, 3.53 g) and the reaction mixture was treated to afford the desired compound (32.3 g) as a syrup.
