Synthetic Route of 639091-75-1, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 639091-75-1, name is Methyl 2-(Boc-amino)isonicotinate. This compound has unique chemical properties. The synthetic route is as follows.

A slurry of methyl 2-((tert-butoxycarbonyl)amino)isonicotinate (50.4 g, 200 mmol) in DMF (500 mL) was cooled to 0C and sodium hydride (10.4 g, 60% in mineral oil, 260 mmol) was added portion wise. The mixture was allowed to warm to RT and stirred for 30 min. To the mixture, iodomethane (37.2 g, 262 mmol) was added slowly. The reaction was stirred at RT overnight. The reaction was quenched by addition of aqueous ammonium chloride (100 mL) and diluted with water (400 mL). The mixture was extracted with EA (250 mL x 2). The combined organics were washed with water (100 mL) and brine (100 mL), dried over MgS04 and concentrated. The residue was chromatographed (eluted with 5: 1 of hexane:EA) to give the product as colorless oil (48.9 g, 92%). H NMR (400Hz, CDCI3) d 1.54 (s, 9H), 3.42 (s, 3H), 3.94 (s, 3H), 7.52 (d, 1H), 8.27 (s, 1H), 8.48 (d, 1H).

According to the analysis of related databases, 639091-75-1, the application of this compound in the production field has become more and more popular.
