Introduction of a new synthetic route about 61-70-1

The synthetic route of 61-70-1 has been constantly updated, and we look forward to future research findings.

61-70-1, 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. 61-70-1, name is 1-Methylindolin-2-one belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.

Step 2: Preparation of 1-methyl-5-nitro-1,3-dihydro-indol-2-one 1-Methyl-1,3-dihydro-indol-2-one (Step 1, 2.10 g, 14.3 mmol) is added in portions to 70% nitric acid (10 ml) at -10 C. After the addition is complete, the reaction is allowed to warm to room temperature and then stirred for 5 hours. The mixture is diluted with ice water and the resulting precipitate filtered, washed with water, and dried under vacuum to give the title compound as a brown solid. HPLC r.t. 3.97 min; MS for C9H8N2O3 m/z 193.9(M+H)+.

The synthetic route of 61-70-1 has been constantly updated, and we look forward to future research findings.
