Reaction Steps

MeMgBr (0.96 ml of a 3M solution in diethyl ether, 2.88 mmol) was added dropwise to a solution of ethyl 5-({1-[(4-cyclobutyl-1,4-diazepan-1-yl)carbonyl]azetidin-3-yl}oxy)pyridine-2-carboxylate (386 mg, 0.96 mmol) in diethyl ether (20 ml) at 0° C. The reaction was warmed to room temperature and after 1 hour was quenched and washed with water (2×20 ml), dried (MgSO4) and concentrated under reduced pressure. The crude material was purified by preparative HPLC to give the title compound (179 mg, 37%) as colourless oil and 1-[5-({1-[(4-cyclobutyl-1,4-diazepan-1-yl)carbonyl]azetidin-3-yl}oxy)pyridin-2-yl]ethanone (2.5 mg, 1%) as colourless oil.
