38642-74-9, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 2-Cyano-phenothiazine, cas is 38642-74-9,the thiazines compound, it is a common compound, a new synthetic route is introduced below.

2-cyanophenothiazine (0.74 g, 3.30 mmol) was dissolved in 10 mL of anhydrous DMF. The mixture was cooled to 0 C and 60 % NaH (0.40 g, 9.90 mmol) was added. The dark mixture was stirred at 0 C for an additional 15 mm and Di-tert-butyl dicarbonate (0.90 g, 3.96 mmol) was added. The mixture was stirred at room temperature for 3 h and was diluted with 50 mL of brine. The aqueous layer was extracted with three 25 mL portions of ethyl acetate. The combined organic extract was dried over anhydrous MgSO4 and concentrated under diminished pressure. The crude was purified on a silica gel column (10 cm x 2 cm). Elution with ethyl acetate-hexane (1:9) gave 1 as a pale yellow solid: yield 1.07 g (100%); silica gel TLC R10.26 (ethyl acetate-hexane 1:9); ?HNIVIR (CDC13) 51.49 (s, 9H), 7.16-7.20 (m, 1H), 7.28-7.33 (m, 2H), 7.40 (s, 2H), 7.49 (d, 1H, J= 8.4 Hz) and 7.80 (s, 1H); ?3CI?IvIR 28.1, 83.1, 110.2, 118.2, 126.6, 127.2, 127.3, 127.5, 128.1,129.1, 130.3, 130.6, 137.7, 139.0, 139.1 and 151.8; mass spectrum (APCI), m/z 325.1017 (M+H) (C18H17N202S requires m/z 325.1011).

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 2-Cyano-phenothiazine, 38642-74-9
