The present invention describes novel methods for the synthesis of benzoxazinone compounds which are useful as human immunodeficiency virus (HIV) reverse transcriptase inhibitors. The benzoxazinone of the formula: 
is particularly effective in the treatment of HIV.
                            本发明描述了一种合成苯并噁嗪酮化合物的新方法,这些化合物可用作人类免疫缺陷病毒(HIV)逆转录酶
抑制剂。该式的苯并噁嗪酮在治疗HIV方面特别有效。
