실험 절차

A mixture consisting of 5.6 g of 3-chloro-4-isopropoxyaniline, 3.9 g of methyl 1-methoxycyclopropanecarboxylate and 1.8 g of sodium methoxide in 50 ml of benzene was refluxed for 3 hours. The reaction mixture was concentrated to a volume of 25 ml, poured over ice water, acidified with hydrochloric acid and extracted with ether. The extract was dried, filtered and concentrated. Purification by silica chromatography gave 1.8 g of product as a white crystalline solid; m.p. 86°-87° C.
