| Product | N-(2,3-dihydro-2,2-dimethyl-1H-inden-1-yl)-N'-cyanoformamidine | HCID 178422614 | 96% |
Reaction Steps
250 Parts of 2,3-dihydro-2,2-dimethyl-1H-inden-1-amine were dissolved in 80 parts of ethanol. 150 Parts of ethyl-N-cyanoformamidate were added within 10 minutes and the mixture was heated to reflux. The cooled solution was concentrated, the precipitate was filtered off and dried, yielding 316 parts (96%) of N-(2,3-dihydro-2,2-dimethyl-1H-inden-1-yl)-N'-cyanoformamidine; mp. 164°-167° C.
