4-Toluenesulfonyl chloride → HCID 86610071, compound

Participants

Reaction Steps

Tosyl chloride (3 g) was added portionwise to pyridine (50 ml) at 5° C., followed by a solution of (3R)-3-(3,5-difluorophenyl)-3-[4-(methylsulfonyl)phenyl]propan-1-ol (3.1 g) in pyridine (15 ml) and the resulting mixture was stirred at room temperature for 18 hours. The reaction mixture was poured onto ice/2N HCl and extracted with diethyl ether (×2). The organic extracts were dried and evaporated to dryness to give (3R)-3-(3,5-difluorophenyl)-3-[4-(methylsulfonyl)phenyl]propyl 4-methylbenzenesulfonate as a solid. Yield 2.9 g. NMR (CDCl3): 2.4 (m, 2H), 2.5 (s, 3H), 3.05 (s, 3H), 3.95 (m, 2H), 4.2 (t, 1H), 6.7 9 m, 3H), 7.3 9 m, 4H), 7.75 (d, 2H), 7.85 (d, 2H).
