c.) Preparación de ácido 7-[(1R,2R,3R,5S)-3,5-dihidroxi-2-[(1E,3S)-3-hidroxi-5-fenil-1-penten-1-il]-ciclopentil]-5hepténico, (5Z)-(ácido de bimatoprost):
c1.) Se disuelven 108 g de bromuro de 4-carboxibutilfosfonio (KBFBr) en 800 ml de THF y la solución se enfría hasta 0 -(-5)°C. Se añaden a esta solución en primer lugar 91 g de terc-butilato potásico (KOtBu) y a continuación, 5 después de agitación y enfriamiento hasta (-10) -(-15)°C, la solución de 25 g de lactoltriol en THF. Cuando se alcanza la conversión esperada, la mezcla de reacción se destruye con agua, y a continuación se añade EtOAc. La fase acuosa se lava con EtOAc. La capa acuosa se acidifica con solución de NaHSO4 hasta pH=2 y se extrae con EtOAc. La fase orgánica unida se lava con solución de NaCl al 15%, se seca sobre Na2SO4, se filtra y se evapora. El residuo se cristaliza en la mezcla de acetato de etilo y éter diisopropílico. Los cristales se separan por filtración y se
10 lavan, la solución del filtrado se evapora. El aceite amarillo resultante se purifica mediante cromatografía sobre gel de sílice usando eluyente de éter diisopropílico – acetona. Se obtienen 25,5 g de aceite.
El espectro IR del ácido de bimatoprost obtenido se muestra en la Figura II.
c2.) El producto obtenido en el ejemplo 1/c1.) se disuelve en 60 ml de acetato de isopropilo y bajo agitación se añaden a esto 40 ml de éter dietílico. Se añade a la mezcla de reacción una pequeña cantidad de ácido cristal de
15 siembra de ácido de bimatoprost. Bajo agitación gradualmente enfriada hasta 0°C, se añaden a esto aproximadamente 60 ml de éter diisopropílico. La suspensión se agita a esta temperatura durante una noche, después de lo cual se filtra y se lava con éter diisopropílico y se seca bajo vacío. Se obtienen 20,4 g de bimatoprost cristalino.
La curva de DSC del ácido de bimatoprost obtenido se muestra en la Figura X y la curva de difracción de rayos X del 20 polvo en la Figura IX.
