Participants

Reaction Steps

A solution of 1,2,3,4-tetrahydronaphthalen-1-ol (248 mg) in DMSO (3 ml) was added to NaH (100 mg) suspended in DMSO (4 ml). The reaction mixture was stirred at r.t. for 1 hour and heated at 75° C. for 1 hour. 2-bromo-5-(2,4-dichlorophenyl)-3,6-diethylpyrazine in DMSO (3 ml) was added. After 24 h, the rxn mixture was diluted with 30 ml of H2O, extracted with CH2Cl2, washed with NaHCO3, brine, dried (MgSO4), filtered and concentrated. Flash chromatography (1:50 EtOAC:Heptane) gave the title compound: 1H NMR (CDCl3) δ 1.23, 1.95, 2.13, 2.20, 2.58, 2.83, 2.96, 6.46, 7.36; HRMS (ESI+) calcd for C24H24Cl2N2O1 (M+H)+ 427.1344, found 427.1359.
