After stirring at this temperature for 35 minutes, 7.3 ml of triisopropyl borate are added. After one hour, 50 ml of 1 N HCl are added to the reaction mixture at -78°C, and the mixture is warmed to room temperature. The phases are separated and the aqueous phase is extracted three more times with 100 ml of diethyl ether each time. The combined organic phases are dried with sodium sulphate, and the solvent is concentrated to 5 ml. The residue is mixed with 150 ml of pentane. The precipitate which has separated out is filtered off with suction and washed twice with pentane. Drying under high vacuum results in 2.85 g of the title compond as a pale yellow solid. Rt = 2.98.

A solution of intermediate 27 (21 mg, 0.050 mmol), 3-cyano-4-methylphenylboronic acid (10 mg, 0.062 mmol), Pd(dppf)Cl2*CH2Cl2 (2.7 mg, 0.003 mmol) and DIPEA (40 μL, 0.230 mmol) in aqueous dioxane (0.55 mL, 10% H2O) was heated at 80° C. under N2 atmosphere for 15 h. The reaction mixture was diluted with MeCN, filtrated and purified by preparative reverse-phase HPLC using basic conditions. The pure fractions were combined and the solvent was removed under reduced pressure giving a mixture of tert-butyl (S)-2-((R)-(2-(3-cyano-4-methylphenyl)quinolin-4-yl)(hydroxy)methyl)piperidine-1-carboxylate and tert-butyl (R)-2-((S)-(2-(3-cyano-4-methylphenyl)quinolin-4-yl)(hydroxy)methyl)piperidine-1-carboxylate (8.5 mg).
