The author of 《A new synthesis of azolooxazines》 were Lupo, B.; Tarrago, G.. And the article was published in Synthetic Communications in 1982. COA of Formula: C5H8N2O The author mentioned the following in the article:
Pyrazolooxazine derivative I was prepared from 3(5)-hydroxymethyl-5(3)-methylpyrazole (II) in two steps. II was heated with propargyl bromide in DMF to yield a mixture of III (R = CH2OH, R1 = Me) and III (R = Me, R1 = CH2OH) (IV). A mixture of IV, Bu4N+ Br-, and NaOH in C6H6 was stirred 4 h at 60° to give I. In the experiment, the researchers used many compounds, for example, (3-methyl-1H-pyrazol-5-yl)methanol(cas: 29004-73-7COA of Formula: C5H8N2O)
(3-methyl-1H-pyrazol-5-yl)methanol(cas: 29004-73-7) belongs to pyrazoles. Pyrazoles and their related multiring analogs are common elements of a wide variety of bioactive compounds. These ring structures are rare in nature. A consequence of this is that they have previously been thought to be poor moieties to include in potential new drugs. COA of Formula: C5H8N2O
