The present invention is directed to an improved process for the preparation of Compounds of Formula (I) or salts thereof which are useful in the treatment of HIV infection. In particular, the present invention is directed to an improved process for the preparation of (2S)-2-tert-butoxy-2-(4-(2,3-dihydropyrano[4,3,2-de]quinolin-7-yl)- 2-methylquinolin-3-yl)acetic acid or salt thereof which is useful in the treatment of HIV infection. R4 is selected from the group consisting of (a), (b), (c), (d), (e), (f), (g), (h), (i), (j), (k), (l), (m), (n) and (o); and R6 and R7 are each independently selected from H, halo and (C1-6) alkyl.
本发明涉及一种改进的工艺,用于制备化合物的化合物(I)或其盐,该化合物在治疗HIV感染中有用。具体而言,本发明涉及一种改进的工艺,用于制备对治疗HIV感染有用的(2S)-2-叔丁氧基-2-(4-(2,3-二氢吡喃并[4,3,2-de]喹啉-7-基)-2-甲基喹啉-3-基)乙酸或其盐。其中R4从(a)、(b)、(c)、(d)、(e)、(f)、(g)、(h)、(i)、(j)、(k)、(l)、(m)、(n)和(o)组成的群中选择;R6和R7分别独立选择自H、卤素和(C1-6)烷基。
