Procedure: To an ice cooled solution of 1-(5-bromo-2-fluorophenyl)-2,2-difluoropropane-1,3-diol (17.0 g, 59.8 mmol) in dry DCM (200 mL) was added imidazole (12.2 g, 179.2 mmol) at 0° C. and stirred for 15 min. tert-butyldimethylsilylchloride (13.5 g, 89.5 mmol) was added to the resultant reaction mixture portion wise for a period of 30 min. and stirring continued for 2 h. Reaction was monitored by TLC analysis. The solids formed in the reaction mixture were separated by filtration and filtrate was concentrated under reduced pressure to obtain crude product which was purified by column chromatography on silica gel with 2% Ethylacetate in Hexane as eluent to furnish title compound as a colorless liquid. Yield=19 g (80%). TLC (20% ethyl acetate in Hexane): Rf=0.75), was added to the resultant reaction mixture portion wise for a period of 30 min. Reaction The solids formed in the reaction mixture were separated by filtration and filtrate was concentrated under reduced pressure to obtain crude product which was purified by column chromatography on silica gel with 2% Ethylacetate in Hexane as eluent

Procedure: To a solution of ethyl 3-(5-bromo-2-fluorophenyl)-2,2-difluoro-3-hydroxypropanoate (20.0 g, 61.3 mmol) in MeOH (160 mL), NaBH4 (7.0 g, 184.2 mmol) was added portion wise over a period of 30 min. at 0° C. Stirring was continued for 1 h at 0° C. and reaction was monitored by TLC. Upon complete consumption of the starting material, reaction mass was concentrated under reduced pressure and treated with saturated ammonium chloride solution. The crude reaction mass was dissolved in ethyl acetate and organic layer was washed with brine (15 mL) followed by drying over anhydrous Na2SO4. The organic layer was concentrated under reduced pressure to furnish title compound with sufficient purity. Yield=17 g (97%). TLC (50% ethyl acetate in Hexane): Rf=0.32), reaction Upon complete consumption of the starting material, reaction mass was concentrated under reduced pressure treated with saturated ammonium chloride solution The crude reaction mass organic layer was washed with brine (15 mL) by drying over anhydrous Na2SO4 The organic layer was concentrated under reduced pressure
