Calculate Digit Verification of CAS Registry Number 119321-48:
(8*1)+(7*1)+(6*9)+(5*3)+(4*2)+(3*1)+(2*4)+(1*8)=111
111 % 10 = 1

SYNTHESIS OF 1,4-BENZODIAZEPINES AND QUINAZOLINES BASED ON CROWNED o-AMINO KETONES

Ivanov, E.I.,Polishchuk, A.A.,Ivanova, R.Yu.

, p. 1337 - 1339 (2007/10/02)

Cyclization of the o-amino ketone derivatives of dibenzo-18-crown-6 ether gave the corresponding crown-annelated 1,4-benzodiazepines and quinazolines. 1,4-Benzodiazepines containing the macrocyclic ring were obtained from the initial o-amino ketones and the acid chloride of glycine hydrochloride or bromoacetyl bromide followed by treatment with ammonia.A convenient method for the synthesis of the quinazolines is cyclization of the o-amino ketones in formamide.
