Versuchsvorschrift

(S)-Pentan-2-yl 2-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl-carbamate (20 mg) and N-(((trans)-4-(1-bromo-8-methylimidazo[1,5-a]pyrazin-3-yl)cyclohexyl)methyl)acetamide (20 mg) were reacted according to the procedure described in example 4 step 4c and purified by prep-HPLC (column Luna C18(2); gradient acetonitrile/water with constant 0.003M trifluoroacetic acid). Proper fractions were collected and made basic with aqueous sodium hydrogencarbonate, extracted with dichloromethane, organic layer dried (Na2SO4) and concentrated in vacuo to give (S)-pentan-2-yl 4-(3-((trans)-4-(acetamidomethyl)cyclohexyl)-8-methylimidazo[1,5-a]pyrazin-1-yl)-2-methoxyphenylcarbamate (16 mg).
