Reaction Steps

To a solution of 1-(3,4-dihydroisoquinolin-2(1H)-yl)-3-(3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy)propan-2-ol (250 mg, 0.61 mmol) in Dioxane (3 mL) was added 3-bromoquinoline (127 mg, 0.61 mmol), 2N K2CO3 (1 mL, 2 mmol) and PdCl2(dppf)2 (20 mg, 0.025 mmol). The reaction mixture was heated at 120° C. under microwave conditions for 30 min. the mixture was then concentrated to remove the solvents, the residue dissolved in ethyl acetate and washed with water. The separated organic layer dried and concentrated to yield the crude product which was purified HPLC separation to give the title compound (133 mg, 53.2%). 1HNMR (CH3OD, 400 MHz) δ: 9.39 (s, 1H), 9.12-9.08 (m, 1H), 8.28-8.19 (m, 2H), 8.06-8.00 (m, 1H), 7.90-7.84 (m, 1H), 7.88-7.46 (m, 3H), 7.36-7.20 (m, 4H), 7.18-7.12 (m, 1H), 4.78-4.40 (m, 3H), 4.23-4.16 (m, 2H), 4.02-4.80 (m, 1H), 3.65-3.40 (m, 3H), 3.40-3.20 (m, 2H). LCMS (m/z): 411.2 [M+H]
