Clomipramine 2 (0.503 g; 1.43 mmol; 1 equiv) was mixed with Cs2CO3 (1.13 g; 3.57 mmol; 2.5 equiv) and XPhos precatalyst PdG1 (0.0313 g; 0.0428 mmol; 3 mol %) in a glove box. To this anhydrous acetonitrile (4 mL) was added, and the reaction mixture was left with stirring, in the glove box for 25 min before THP protected propargyl alcohol (0.501 g; 3.57 mol; 2.5 equiv) was added. The reaction vessel was sealed, removed from the glove box, and then heated to 80 C for 20 h. After 20 h the reaction mixture was cooled to rt and quenched with saturated NaHCO3 (aq). The mixture was extracted with AcOEt, and the combined organic phases were dried over MgSO4, filtered and evaporated. The product was purified by column chromatography (first CH2Cl2/CH3OH 50:1 then CH2Cl2/CH3OH 20:1). Upon repeated column chromatography, the product was isolated as brown oil in 63% yield (0.375 g; 0.895 mmol). Rf (CH2Cl2/CH3OH 20:1) 0.45. 1H NMR (400 MHz, CDCl3) deltaH 7.16-7.02 (m, 4H), 6.99 (s, 2H), 6.94 (dt, 1H, J = 7.3, 1.1 Hz), 4.88 (t, 1H, J = 3.4 Hz) 4.46 (q, 2H, J = 15.7 Hz), 3.93-3.81 (m, 1H), 3.77 (t, 2H, J = 6.6 Hz), 3.61-3.50 (m, 1H), 3.12 (s, 4H), 2.60 (t, 2H, J = 5.6 Hz), 2.35 (s, 6H), 1.96-1.48 (m, 8H). 13C NMR (100 MHz, CDCl3) deltaC 147.9, 134.9, 134.4, 130.3, 129.7, 126.7, 125.9, 123.3, 123.2, 120.7, 120.4, 96.9, 86.0, 84.4, 62.1, 57.3, 54.9, 48.5, 44.9, 32.6, 31.8, 30.4, 25.5, 19.2 ppm.
