To dry THF (20 mL) was added NaH (60% in mineral oil, 2.37 g, 59.14 mmol). Then the mixture was stirred at 27° C. for 20 minutes, then tert-butyl 1-(3-hydroxybutan-2-yl)-2-methyl-1H-pyrrolo[2,3-b]pyridine-3-carboxylate (3.0 g, 9.86 mmol) was added. The mixture was stirred at 27° C. for 1 hour, then added by CH3I (13.99 g, 98.6 mmol). The mixture was stirred for 12 hours at 27° C. and then cooled to 0° C. Sat. NH4Cl was added and extracted with CH2Cl2. The extraction was dried over sodium sulfate, filtered and concentrated to give tert-butyl-1-(3-methoxybutan-2-yl)-2-methyl-1H-pyrrolo[2,3-b]pyridine-3-carboxylate as a yellow oil. (3.2 g, yield 100%) LCMS (M+H+) m/z: calcd. 319.41. found 318.9.
