A common heterocyclic compound, 79463-77-7, name is Diphenyl N-cyanocarbonimidate, molecular formula is C14H10N2O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. 79463-77-7.
To a solution of N-(2-dimethylaminoethyl)-2,5-dimethoxybenzene 1,4-diamine hydrochloride (0.05g, 0.143mmol) in distilled water (1mL) was added K2CO3 (0.065g, 0.47mmol). This was diluted with EtOAc (1mL) and diphenylcyano-carbonimidate (0.032g, 0.136mmol) was added. The reaction was stirred at RT for 18h. The precipitate was filtered and washed with minimal EtOAc to give the title compound as a light purple solid (0.015g, 29% yield). 1H-NMR (500 MHz, DMSO-d6) 10.11 (s, 1H), 7.51-7.33 (m, 2H), 7.31-6.98 (m, 3H), 6.81-6.64 (m, 1H), 6.28 (br s, 1H), 4.87 (br s, 1H), 3.85-3.62 (m, 5H), 3.12 (s, 3H), 2.17 (s, 6H) ppm; LC-MS 384.3 (M+H); HPLC 1.9 min(method A).
The synthetic route of Diphenyl N-cyanocarbonimidate has been constantly updated, and we look forward to future research findings.
