Reaction Steps

DABCO (2 mg) was added to a mixture of methyl 5,6-dichloronicotinate (27 mg, CAS. Reg. No. 56055-54-0), 3-chloro-4-(3,3,3-trifluoro-2-hydroxy-1-methyl-2-quinoxalin-6-yl-propyl)-phenol (50 mg), and triethylamine (17 mg) in DMF (5 ml). The mixture was stirred at room temperature overnight. Aqueous LiOH solution (1N, 1 ml) was added and then stirred for 2 hours to hydrolyze the intermediate ester. The mixture was purified by prep. HPLC (C18-column, solvent gradient 20-98% CH3CN in 0.1% HCOOH[aq]) to give the title compound (10 mg) as a white foam. MS (m/e)=536.1 [M+H+].
