Procedure
A solution of 9.0 g of 4-(cyclohexylamino)-1,2-naphthoquinone in 200 ml of dimethyl sulfate and 460 ml of 30% aqueous sodium hydroxide is heated slowly to reflux. The reaction mixture is stirred for 6 hours, washed with 300 ml of water and dried at 80° C. under vacuo to yield 4-cyclohexylimino-1-oxo-2-methoxy-1,4-dihydronaphthalene, m.p. 145°-147° C.
