1,2,3,4-Tetrahydroisoquinoline → HCID 18763653, compound

Participants

Reaction Steps

A mixture of 4-chloro-2,6-dimethylpyrimidine (Chem. Ber. 1902, 35, 1575; 1.24 g, 8.70 mmol) and 1,2,3,4-tetrahydroisoquinoline (3.47 g, 26.1 mmol) was stirred at room temperature for 3 h. The solid formed was then dissolved in toluene (15 ml) and 1 M aqueous potassium phosphate buffer (pH 6.85, 15 ml). The organic layer was separated, washed with brine, dried (MgSO4), and evaporated. Recrystallization in hexane (150 ml) yielded 2-(2,6-dimethyl-pyrimidin-4-yl)-1,2,3,4-tetrahydro-isoquinoline (1.71 g, 82%) as a crystalline light yellow solid. EI mass spectrum, m/e: 239.1 (M calculated for C15H17N3: 239).
