Методика

A mixture of ((2S,3R)-2-(((5-bromoquinazolin-2-yl)amino)methyl)-3-methylpiperidin-1-yl)(5-methyl-2-(2H-1,2,3-triazol-2-yl)phenyl)methanone (0.057 g, 0.111 mmol), HCOONH4 (0.14 g, 0.222 mmol) and Pd(PPh3)4 (0.026 g, 0.022 mmol) in dioxane and water (4:1, 2 mL) was heated for 2 h at 100° C. The mixture was cooled to rt and filtered through diatomaceous earth. The solvent was removed and the crude residue was purified via silica gel chromatography to obtain the title compound. ESI-MS (m/z): 442 [M+1]+.
