The aqueous layer was separated and washed with 12 mL of dichloromethane. The aqueous layer was charged into another flask and 40 mL of dichloromethane and 20 mL of 16% aqueous sodium hydroxide solution was added drop-wise at 26° C. The mixture was stirred for one hour at 26° C. and the organic layer was separated and the aqueous layer was extracted with 20 ml of dichloromethane. Combined the organic layers and evaporated under vacuum at below 45° C. Isopropyl alcohol (8 mL) was added to the residue and evaporated under vacuum at below 45° C. Isopropyl alcohol (16 mL) was added to the residue and stirred for 2 hours at 26° C. Filtered the compound and washed with isopropyl alcohol (4 mL) and dried the compound at 60° C. under vacuum to give 3.2 gm of Linagliptin.

Potassium carbonate (778 mg, 5.6 mmol) was added to a stirred solution of 3-cyclobutyl-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ol (E3) (868 mg, 4.0 mmol), 2,4-difluorobenzyl bromide (0.25 ml, 2.1 mmol) and potassium iodide (25 mg) in butanone (9 ml). The reaction mixture was stirred at reflux for 18 hours, cooled, filtered and concentrated in vacuo. The crude residue was dissolved with ethyl acetate and washed with water and brine. The organic layer was dried over magnesium sulfate, filtered and concentrated in vacuo. Purification of the resulting residue by column chromatography eluting with a mixture of 0.880 ammonia:ethanol:dichloromethane (0.25:2.25:97.5 then 1:9:10) afforded the title compound (E79); MS (ES+) m/e 344 [M+H]+.

Procedure:
To a solution of (3S,4S)-4-carboxy-3-(1-(R)-hydroxyethyl)-1-di(p-anisyl)methyl-2-azetidinone (34 g) in methanol (310 ml), there was added 98% sulfuric acid (2.9 g). The resultant mixture was heated at 65° C. for 3 hours, cooled down to 40° C., neutralized with 8% aqueous sodium hydroxide solution (15 ml) and concentrated to make a one third volume. The concentrate was diluted with 1,2-di-chloroethane (105 ml) and washed with water. The aqueous layer was separated from the organic layer and extracted with 1,2-dichloroethane (105 ml). The extract was combined with the organic layer, washed with water and dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated in vacuo to give (3S,4S)-4-methoxycarbonyl-3-(1-(R)-hydroxyethyl)-1-di(p-anisyl)methyl-2-azetidinone. m.p., 102°-104° C.
