A railroad accident in Somerville, Massachusetts, led to spillage of phosphorus trichloride liquid. Attempted clean-up with water led to the liberation of phosphorus trichloride, phosphoric acid, hydrochloric acid, and phosphorus oxides. Seventeen people exposed to this mixture were studied.

A protocol for the synthesis of N-substituted 2-hydro-4-amino-pyrido[2,3-d]pyrimidin-7(8H)-ones (11) is described. Thus, the formylation of a 2-aminopyridone 12 in 85% formic acid/Ac(2)O, proceeding via in situ cyclization to the intermediate formamide 13, affords the corresponding 2-hydro-4-oxo-pyridopyrimidine 14, which is converted
