Reaction Steps

124.00 mg of N′-[5-(1-methyl-1H-pyrazol-4-yl)-2-pyrimidyl]phenylacetohydrazide are suspended in 2.5 ml of tetrahydrofuran in an N2-flushed reaction vial provided with a magnetic stirrer, 127.86 mg of triphenylphosphine and 66.81 μl of azidotrimethylsilane are added, and 120.84 μl of diisopropylazo dicarboxylate are added. The mixture is stirred at RT for a further 2 h. The reaction mixture is adsorbed onto silica gel and chromatographed. The chromatography residue is crystallised using methanol, filtered off with suction and dried.
