For example, between 2010 and 2018, outputs of chemicals and their products in Indonesia, Malaysia, the Philippines, Singapore, Thailand, and Vietnam, increased in value by nearly 40 per cent from US$132 billion to US$181 billion. [5] Examples of such precursors and drugs made with them are listed below.
1-Phenylethylamine may be prepared by the reductive amination of acetophenone: [1]. C 6 H 5 C(O)CH 3 + NH 3 + H 2 → C 6 H 5 CH(NH 2)CH 3 + H 2 O. The Leuckart reaction, using ammonium formate, is another method for this transformation.
Benzyl is most commonly abbreviated Bn. For example, benzyl alcohol can be represented as BnOH. Less common abbreviations are Bzl and Bz, the latter of which is ambiguous as it is also the standard abbreviation for the benzoyl group C 6 H 5 C(O)−.
