Participants

Reaction Steps

4-Aminomethyl-cyclohexylmethyl-amine (cis/trans-mixture, ca. 2:1) (1.28 g, 9.00 mmol) is added to a stirred suspension of 4-benzo[b]thiophen-2-yl-2-chloro-pyrimidine (986 mg, 4.00 mmol) in isopropanol (13 mL) at ambient temperature under nitrogen. The resultant mixture is heated at 110° C. for 20 hours. At ambient temperature the mixture is diluted with dichloromethane (40 mL), washed with 1N NaOH (13 mL), and dried (MgSO4). After concentration and subsequent chromatographic purification on silica gel, eluting with 2 M NH3/MeOH in dichloromethane 0-20%, the title compound is obtained as a 2:1 cis/trans-mixture (1.24 g, 88% yield). ES+(m/z) 353 [M+H].
