Reaction Steps
850 mg of the compound prepared in step B are dissolved in 15 ml of DMF, and equimolar amounts of 4-aminomethyl-2'-tert-butoxycarbonylbiphenyl, DIPEA and then BOP (10% excess) are added. After 40 minutes, the medium is taken up in 200 ml of ethyl acetate and 200 ml of water. The organic phase is decanted and then washed twice with a saturated solution of sodium bicarbonate, twice with a 5% solution of sodium bisulfate and then once with a saturated solution of sodium chloride. After drying over sodium sulfate, the organic phase is evaporated under vacuum to give 1.8 g of the expected product.
