Water → 5-{7-(2-chloro-4-pyridyl)-8-(3-(trifluoromethyl)phenyl)-1,2,4-triazolo[4,3-c]pyrimidin-5-yl}-2-(tert-butoxycarbonyl)-(1R)-2,5-diaza-bicyclo[2.2.1]heptane

Participants

Reaction Steps

A mixture of 5-chloro-7-(2-chloro-4-pyridyl)-8-(3-(trifluoromethyl)-phenyl)-1,2,4-triazolo[4,3-c]pyrimidine (820 mg, 2.0 mmole), potassium carbonate (ca. 1.0 g) and (−)-2-(tert-butoxycarbonyl)-(1R, 4R)-2,5-diaza-bicyclo[2.2.1]heptane (436 mg, 2.2 mmole) in 10 ml of DMF was stirred at room temperature for 16 hours. The reaction solution was poured into water (50 mL), and precipitate was filtered and washed with water and dried under vacuum to give product as off white solid; MS m/z (M)+ 572.3; C27H25ClF3N7O2 requir. 572.
