反応手順

A solution of 7.00 g of (2-amino-5-methoxyphenyl)methanol, 9.8 ml of formic acid cyanomethyl ester and 0.05 g of 4-N,N-(dimethylamino)pyridine in 30 ml of anhydrous tetrahydrofuran was heated for 5 hours under reflux. The solution was then concentrated by evaporation in vacuo and the residue was taken up in 100 ml of ethyl acetate. Crystals formed on cooling the solution to 0° C., which were suction filtered, washed with methanol, and dried in vacuo. 7.20 g (75% of theory) of the title compound were thereby obtained.
