PROCEDURE

实验过程

A mixture of (S)-1-[5-tert-Butyl-3-(2-chloro-pyridin-3-ylmethyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidin-7-yl]-pyrrolidin-3-ol (example 140) (5.30 mg, 13.7 μmol), 7-nitrobenzo[c][1,2,5]oxadiazol-4-amine (2.95 mg, 16.4 μmol), Pd2(dba)3 (1.25 mg, 1.37 μmol), xantphos (2.15 mg, 3.71 μmol) and Cs2CO3 (8.06 mg, 24.8 μmol) in dioxane (500 μl) was heated to 120° C. and stirred for 20 min. The crude material was filtered (celite), concentrated and purified by preparative HPLC eluting with a gradient formed from acetonitrile, water and NEt3. The product containing fractions were evaporated to yield 1.2 mg (16%) of the title compound as red solid. MS(m/e): 532.4 (MH+).
