Reaction Steps

To a solution of ethyl 2-((2-methoxyethoxy)methyl)thiazole-4-carboxylate (Example 6C, 2.27 g, 9.25 mmol) in ether (50 mL) was added portion wise lithium aluminum hydride (1.06 g, 27.9 mmol) over 10 min. at −78° C. The reaction was then stirred at −78° C. for 1 hour. Ethyl acetate (10 mL) was then added to the reaction followed by water (20 mL) and the reaction was allowed to reach RT. The mixture was then diluted with ethyl acetate, washed with HCl 1N (1×) and brine (1×). The combined aqueous phases were extracted with ethyl acetate (2×300 mL), dried over anhydrous magnesium sulfate, filtered and concentrated. The residue was purified by silica gel chromatography (3.5×10 cm, ethyl acetate) to give the title material (0.357 g, 19%) as a brown oil. LC (Method F): 1.791 min. 1H NMR (CDCl3, 400 MHz) δ ppm: 7.16 (s, 1H), 4.82 (s, 2H), 4.74 (broad s, 2H), 3.7-3.75 (m, 2H), 3.54-3.61 (m, 2H), 3.38 (s, 3H), 2.28 (broad s, 1H).
