Reaction Steps

A mixture of (2R)-4-(7-chlorothieno[3,2-b]pyridin-6-yl)but-3-yn-2-ol (0.055 g, 0.23 mmol), (trans-4-aminocyclohexyl)acetonitrile hydrochloride (0.040 g, 0.23 mmol), cesium carbonate (0.19 g, 0.58 mmol), palladium acetate (5.2 mg, 0.023 mmol) and (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (27 mg, 0.046 mmol) in toluene (1.1 mL) was purged with N2 for 3 times. The resulting mixture was stirred at 100° C. for 2 h, then at 120° C. for 2 h. The mixture was filtered. The filtrate was concentrated under reduced pressure, diluted with MeOH and purified on prep-LCMS (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.1% ammonium hydroxide, at flow rate of 30 mL/min) to give the desired product (1.4 mg, 1.8%). LCMS calculated for C19H22N3OS (M+H)+: m/z=340.1. Found: 340.1.
