The synthetic route of 3100-67-2 has been constantly updated, and we look forward to future research findings.

Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 3100-67-2, name is 1-Amino-2-naphthonitrile, A new synthetic method of this compound is introduced below., Quality Control of 1-Amino-2-naphthonitrile

A solution of 1-amino-2-naphthonitrile (1.00 g, 5.95 mmol) in anhydrous ether (20 mL) was dropwise added to a solution of 1M 3-methoxyphenylmagnesium bromide-tetrahydrofuran solution (17.8 mL, 17.8 mmol) for 10 minutes. The mixture was heated under reflux for one hour. The reaction mixture was poured into 2N hydrochloric acid (30 mL). After addition of methanol (5 mL), the mixture was stirred for 4 hours at room temperature. The mixture was neutralized by addition of potassium carbonate, and the neutralized ether was subjected to extraction with ether. The ether portion was washed with saturated brine and dried over anhydrous sodium sulfate. The dried mixture was placed under reduced pressure to distill the solvent off. The residue was purified by silica gel column chromatography (chloroform/hexane=4/1), to give the titled compound (1.54 g, yield 93%). 1H NMR (CDCl3, 400 MHz) delta: 3.85 (3H, s), 6.98 (1H, d, J=9Hz), 7.06 (1H, dd, J=2, 8Hz), 7.1-7.2 (2H, m), 7.37 (1H, t, J=8Hz), 7.4-7.6 (4H, m), 7.5-7.6 (1H, m), 7.74 (1H, d, J=8Hz), 7.97 (1H, d, J=8Hz).

The synthetic route of 3100-67-2 has been constantly updated, and we look forward to future research findings.
