Reaction Steps
To a solution of 2-bromo-3',4'-difluoropropiophenone (47.3 g, 0.19 mole) in acetonitrile (100 ml) was added a solution of R-2-amino-1-propanol (Aldrich Chemical Co., Milwaukee, Wis. 53233) (15 g, 0.20 mole) and 2,6lutidine (23.69, 0.22 mole) in acetonitrile (50 ml). The reaction was worked up as in Example 1 to give 26.9 g of (2S, 3S, 5R)-2-(3,4difluorophenyl)-3,5-dimethyl-2-morpholinol hydrobromide.
