摘要
以２－氨基－５－硝基二苯酮为原料，经卤乙酰化、环合和成盐精制得硝基安定。比较了氯乙酰氯和溴乙酰溴对中间体及硝基安定收率的影响。
Nitrazepam was synthesized from 2-amino-5-nitrobenzophenone by haloacetylation, cyclization, and purification via salt formation.The effect of chloroacetyl chloride and bromoacetyl bromide on yields of intermediates and nitrazepam was compared.
