Sodium Acetate → HCID 9931357, compound

Participants

Reaction Steps

Sodium acetate (1.2 g), 2,4-dichlorothieno[3,2-d]pyrimidine(0.75 g) and 4'-aminomethyl(1,1'-biphenyl)-2-carboxylic acid methylester hydrochloride (1.02 g) were suspended in 40 mL of tetrahydrofuran. The reaction mixture was stirred at room temperature for 3 days at which time all the THF was removed by evaporation. The residue was partitioned between ethyl acetate and saturated aqueous sodium carbonate. The organic layer was dried over anhydrous magnesium sulfate, filtered and evaporated. The residue was purified on silica gel chromatography (ETOAc/Hexane) to yield the product as a buff powder (0.81 g, 54%) (m.p.=177°-182° C.): 1H NMR (DMSO-d6, 400 MHz) δ8.98 (t, J=6.0 Hz, 1H), 8.19 (d, J=5.4 Hz, 1H), 7.71 (dd, J=1.1; 7.7 Hz, 1H), 7.60 (m, 1H), 7.46 (m, 1H), 7.38 (m, 4H), 7.25 (m, 2H), 4.73 (d, J=5.9 Hz, 2H), 3.58 (s, 3H); positive FAB MS m/e 410 (MH); 376 (M--Cl+H).
