4-Benzyloxy-2-methylphenylboronic acid Use and Manufacturing

Methods of Manufacturing

A mixture of C22 (1.00 g, 3.13 mmol), To a mixture of C3 (10 g, 29 mmol), 49B. 2-((2S, 4S)-1-(4-(4-(benzyloxy)-2-methylphenoxy)phenyl)-4-(trifluoromethyl)pyrrolidin-2-yl)acetonitrile 49A (0.030 g, 0.11 mmol), Step 1 2-AMINO-4- (4-BENZYLOXY-2-METHYL-PHENYL)-THIENO [2, 3-d] pyrimidine-6- carboxylic acid ethyl ester 2-METHYL-4-BENZYLOXYPHENYLBORONIC acid (225 mg; 0.93 MMOL) was added to 2-Amino-4-chloro-thieno [2, 3-d] PYRIMIDINE-6-CARBOXYLIC acid ethyl ester (step 1) (200 mg; 0.776 MMOL) in DMF (10ML). NAHCO3 (1. OM aq. Solution ; 2.33 mL) was added and mixture degassed with N2. PD (PPH3) 2C12 was added and reaction mixture heated at 80 degrees C for 5 hours Reaction mixture was allowed to cool to room temperature and DMF removed in vacuo. The residue was partitioned between ethyl acetate (50 mL) and sat. NaCI (aq) (50 mL) Organic phase was dried over NA2SO4 and filtered, filtrate solvents removed in vacuo to afford a yellow oil which was purified by ion-exchange chromatography (IST SCX-2 column) to afford product as a brown-yellow solid (230 mg ; 71%) LC-MS retention time: 2.852 minutes, [M+H] 420 (Run time 3.75mins)
