Participants

Reaction Steps

3-Chloro-5,6,7,8-tetrahydro-isoquinoline (Chemische Berichte 1948, 81, 279) (8.82 g; 52.6 mmol) dissolved in THF (65 ml) is added under stirring at room temperature to a solution of KOtBu (11.78 g; 105.2 mmol) in THF (100 ml). The red turbid solution is stirred for 12 hours and then cooled to 0° C. tert-Butyl nitrite (18.7 ml; 157.8 mmol) is added dropwise, the reaction mixture is stirred at room temperature for 4 hours and poured on brine. The reaction mixture is extracted with ethyl acetate three times, the organic phases are combined, dried over Na2SO4 and evaporated to dryness, yielding the desired product as brownish crystals. 1H-NMR (400 MHz; DMSO-d6): 11.83 (s, 1H); 8.28 (s, 1H); 7.66 (s, 1H); 2.72 (m, 2H); 2.66 (m, 2H); 1.77 (m, 2H). MS (m/z) ES+: (197, MH+).
