Procedure
A mixture of 14 parts of N-(2-hydroxyphenyl)-N'-(4-pyridinylmethyl)thiourea, 20 parts of mercury(II) oxide, 1 part of sulfur, 160 parts of 2-propanol and 160 parts of acetonitrile was stirred and refluxed for 14 hours. The reaction mixture was filtered over diatomaceous earth and the filtrate was evaporated. The oily residue was crystallized from acetonitrile, yielding 6.8 parts (56%) of N-(4-pyridinylmethyl)-2-benzoxazolamine; mp. 147.9° C. (intermediate 74).
