A solution of 6,7-difluoro-1-indanone (6.00 g, 35.70 mmol), NaBH3CN (15.70 g, 0.25 mol) and NH4OAc (82.60 g, 1.07 mol) in isopropanol was reacted according to the protocols as outlined in general procedure B to give 3.00 g of the crude title compound, which was used in the next step without further purification. Spectroscopic data: 1H NMR (300 MHz, CDCl3) □ 1.7 (br s, 2H), 1.78-1.90 (m, 1H), 2.44-2.57 (m, 1H), 2.72-2.87 (m, 1H), 2.95-3.09 (m, 1H), 4.7 (t, 1H, J=6.7 Hz), 6.86-7.00 (m, 2H).
