Participants

Reaction Steps

To a solution of phosphorus oxychloride (1.68 ml, 18 mmoles) and 1,2,4-triazole (4.96 g, 72 mmoles) in dry pyridine (110 ml) was added the compound of example 49 (2.45 g, 7.18 mmoles). The suspension was stirred at room temperature for 4 hours. The precipitate was filtered off, washed with pyridine, toluene and diethyl ether. The resulting solid was dried over P2O5 under vacuum, providing the title compound as a yellow powder (2 g, yield: 80%) which afforded the following mass spectrum: 392 ([M+H]+, 100).
