반응 단계

2 g of potassium borohydride were added in small fractions at +5° C. to a solution of 4.6 g of the product of Step A, 150 ml of tetrahydrofuran and 30 ml of water and the mixture was stirred for one hour. The mixture was allowed to return to ambient temperature and the tetrahydrofuran was eliminated under reduced pressure. The resulting mixture was diluted with ether, washed with water, dried and concentrated under reduced pressure. The residue was chromatographed over silica (eluent: hexaneethyl acetate 7-3) to obtain 3 g of 2-trifluoromethyl-(1H)-indol-3-yl methanol melting at 106° C.
