Reaction Steps

A mixture of 4-(benzo[b]thiophen-2-yl)-2-(methylsulfonyl)pyrimidine (75 mg, 0.26 mmol)), 1-(2-aminoethyl)imidazolidin-2-one (33 mg, 0.26 mmol) and triethylamine (32 mg, 0.31 mmol) in methoxyethanol (3 mL) was heated at 100° C. overnight. After cooling to rt the solvent was removed in vacuo and the product was purified by chromatography eluting with methanol/dichloromethane (1:20) to give the title compound as a slightly yellow solid (56 mg, 64%). MS (M+H)+ 340.
