Lithium aluminum hydride in pyridine, lithium borohydride in THF, and sodium borohydride in ethanol all reduced 290 to ethyl 4-substituted-2-methylthio- I ,6-dihydropyrimidines (291). I5lThe intermediacy of the hexahydro derivative 293 was proved by its isolation from the reaction mixture and subsequent conversion to 294 with additional borohydride. l-Phenyl-4,4,6-trimethyldihydropyrimidine (292) may ring open via N-1 -C-2 or C-2-N-3 cleavage. In fact, only the former is observed, presumably a result of the increased stability of the N- I -phenyl anion.
