Reaction Conditions

Reaction Steps

A solution of 1-phenylcyclopropanecarboxamide (0.450 g, 2.79 mmol) in tetrahydrofuran (5 mL) was slowly added to a suspension of LAH (0.117 g, 3.07 mmol) in tetrahydrofuran (5 mL) at 23° C. over 2 minutes. The reaction was then heated to 65° C. for 6 hours. The reaction was quenched with the Rochelle salt (1N in water, 10 mL) and extracted with ethyl acetate (3×). The combined organic layers were then dried over anhydrous magnesium sulfate, filtered and concentrated to give the crude title material (0.200 g, 49%) as an oil which was used as such in the next reaction. An aliquot was purified on preparative HPLC (ammonium acetate/water/acetonitrile). 1H NMR (400 MHz, CDCl3, acetic acid salt) δ: 0.83-0.94 (4H, m), 1.98 (3H, s), 2.90 (2H, s), 4.98 (3H, br s), 7.23-7.37 (5H, m).
