Reference of 98730-77-9,Some common heterocyclic compound, 98730-77-9, name is 1-(Hydroxymethyl)cyclopropanecarbonitrile, molecular formula is C5H7NO, 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.
A stirred mixture of 1-(hydroxymethyl)cyclopropanecarbonitrile (24.30mmoi, 2.36g) in dichioromethane (3OmL) was treated with triethylamine (48.deltammol, 6.83mL, 4.92g) and portiortwise with methanesuifonyl chloride (31.deltammol, 2.445mL, 3.62g) keeping the reaction mixture at O0C. The solution was allowed to stir for 1 hour then diluted with saturated sodium hydrogencarbonate and extracted with 10% methanol/dichloromethane (x3). The organic layers were combined and concentrated under reduced pressure to give the intermediate (i-cyanocydopropyl)methyl methanesutfonate (3.77g).1H NMR (CDCI3, 400 MHz): delta 1.18 (2H, m), 1.46 (2H, m), 3,14 (3H, s), 4.18 (2H, s)
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1-(Hydroxymethyl)cyclopropanecarbonitrile, its application will become more common.
