Procedure

A mixture of 4′-({4-[4-hydroxymethylbenzyl]-5-oxo-7-propyl-4,5-dihydro[1,2,4]triazolo[1,5-a]pyrimidin-6-yl}methyl)biphenyl-2-carbonitrile (1.3 g), manganese dioxide (7.0 g) and methylene chloride (15 mL) was stirred at room temperature for 16 hr. The insoluble material was filtered off through celite, and the filtrate was concentrated to give the title compound as a colorless solid (1.3 g, 96%).

Workup

  1. filtrationThe insoluble material was filtered off through celite
  2. concentrationthe filtrate was concentrated
