to afford the title compound as a pale-yellow solid (0.019 g, 48% Acetone cyanohydrin (0.015 g, 0.173 mmol) solubilized in 0.3 mL of 1-butanol was then added drop-wise over 4 hrs. After the addition was completed the reaction was stirred at room temperature for 18 hrs. Saturated NaHCO3 (2 mL) was then added and the reaction mixture was stirred for 10 min. The aqueous solution was extracted with ethyl acetate (2 x 5 mL). The organic layers were combined, dried over magnesium sulfate, filtered and concentrated. The crude material was purified by flash column chromatography (0-20% ethyl acetate in cyclohexane) to afford the title compound as a white solid (0.039 g, 80%). ¹H NMR (400 MHz, CDCl3): δ 7.56-7.52 (m, 2 H), .
