Reaction Steps

Charge methyl 4-cyano-2-methylbenzoate (627 mg, 3.57 mmol), THF (12 mL) and ethanol (12 mL) to a flask, followed by CaCl2 (418 mg, 3.57 mmol) and NaBH4 (265 mg, 7.16 mmol). The mixture was then stirred at room temperature overnight. Water was added, and the mixture was extracted with ethyl acetate. The organic extract was concentrated and purified by flash column chromatograph to give 325 mg of the title compound (62%). 1H NMR (300 MHz, CDCl3): δ 1.83 (1H, t, J=5.4 Hz), 2.33 (3H, s), 4.75 (2H, d, J=5.4 Hz), 7.43 (1H, s), 7.52-7.56 (2H, m).
