Treatment of methyl N-methylcarbaaate (1, R= Me) with phosphorus oxychloride and 1-naphthol results in the formation of the transesterified product, 1-naphthyl N-methylcarbamate (2, Ar=1-naphthy 1) in good yield. Similarly, ethyl N-methylthiocarbamate (5) is converted to 1-naphthyl N-methylcarbamate (2, Ar= 1-naphthyl) on treatment with phosphorus oxychloride and 1-naphthol. The mechanism of these interesting and industrially important transformations is discussed.
