Procedure
As in Example 111, 1-butyl-3,4-dihydro-6-methoxy-2-naphthalenecarboxaldehyde (3.05 g) and (carbomethoxymethylene)triphenylphosphorane (4.5 g) in dichloromethane (25 mL) was stirred at room temperature for 64 hours. The usual work up furnished 2.9 g of (E)-3-(1-butyl-3,4-dihydro-6-methoxy-2-naphthalenyl)-2-propenoic acid methyl ester as an oil.
