Reaction Conditions

Reaction Steps

To 1-(2-methoxyphenyl)cyclobutanecarbonitrile (4.29 g) was added sulfuric acid (20 mL, 95-98%)/water (20 mL) and the reaction warmed to 60° C. After 1 h the solution was warmed to 80° C. and heating was continued for 3 h. The reaction was cooled to room temperature and stirred for 16 h. Heating was resumed and after 1 h acetic acid (10 mL) was added. The temperature was increased to 90° C. and heating was continued for 1.75 h. The reaction was cooled to room temperature and then poured onto ˜300 ml of ice and extracted with ethyl acetate. The organic layer was dried (Na2SO4) and the solvent removed in vacuo to afford the subtitle product (4.19 g).
