Procedure

Under a nitrogen atmosphere, 0.4 ml triethylamine was added to 1.5 ml methylamine (2 M in THF) in 20 ml dry toluene. To the resulting solution was cooled to 5° C. and 250 mg 2-chloronaphtho[1,8-de][1,3,2]dioxaphosphinine (available from Hansa Fine Chemicals GmbH, Bremen, Germany) was slowly added. After stirring overnight at room temperature 20 ml hexane was added. The precipitate was removed by centrifugation. The solvents were removed under vacuum. The product N-methylnaphtho[1,8-de][1,3,2]dioxaphosphinine-2-amine was isolated as an oil and used as such. 31P-NMR C6D6 δ 121.2.
