Abstract

Reivindicacion 1: Un proceso para el aislamiento de un compuesto de formula (1) o un solvato de dicho compuesto, a partir de una mezcla que comprende un compuesto de formula 1 y un compuesto de formula (2), donde, de manera independiente en cada aparicion: R1 representa H o alquilo C1-6; R2 representa fenilo o piridilo, donde ambos grupos están opcionalmente sustituidos con uno o más sustituyentes seleccionados de -OH, ciano, halo, nitro, alquilo C1-6 (opcionalmente terminado por - N(H)C(O)OR3a), alcoxi C1-6, N(R4a)R4b, -C(O)R4c, -C(O)OR4d, -C(O)N(R4e)R4f, -N(R4g)C(O)R4h, -N(R4i)C(O)N(R4j)R4k, -N(R4m)S(O)2R3b, -S(O)2N(R4n)(R4o), -S(O)2R3c, -OS(O)2R3d y/o arilo; R3a a R3d independiente representan alquilo C1-6; R4a y R4b independientemente representan H, alquilo C1-6 o juntos representan alquileno C3-6, lo que da como resultado un anillo de entre cuatro y siete miembros que contiene nitrogeno; R4c a R4o independientemente representan Ho alquilo C1-6; donde cada grupo arilo, a menos que se especifique lo contrario, está opcionalmente sustituido; proceso que comprende: a) (i) preparar una solucion de mezcla de los compuestos de formulas 1 y 2 en un sistema solvente que comprende un hidrocarburo aromático; (ii) co-cristalizar los compuestos de formulas 1 y 2 a partir de esa solucion, con lo cual se produce una mezcla de material cristalino y licor madre; (iii) calentar la mezcla resultante para disolver selectivamente el compuesto cristalino de formula 1 en el licor madre; (iiii) separar la fase de solvente y el producto cristalino resultantes; y (iiiii) cristalizar el compuesto de formula 1 contenido en la fase solvente; o b) (i) preparar una solucion de mezcla de los compuestos de formulas 1 y 2 en un sistema solvente que comprende un alcohol de alquilo C2-6; y (ii) cristalizar el compuesto de formula 1 a partir de esa solucion. En donde la mezcla de los compuestos de las formulas 1 y 2 se puede preparar por reaccion de un compuesto de formula 3: R2-OH con un compuesto de formula (4), y en donde R1 y R2 tienen los significados dados en la reivindicacion 1, y L1 representa un grupo saliente.Claim 1: A process for the isolation of a compound of formula (1) or a solvate of said compound, from a mixture comprising a compound of formula 1 and a compound of formula (2), wherein, independently in each occurrence: R1 represents H or C1-6 alkyl; R2 represents phenyl or pyridyl, where both groups are optionally substituted with one or more substituents selected from -OH, cyano, halo, nitro, C1-6 alkyl (optionally terminated by - N (H) C (O) OR3a), C1 alkoxy -6, N (R4a) R4b, -C (O) R4c, -C (O) OR4d, -C (O) N (R4e) R4f, -N (R4g) C (O) R4h, -N (R4i) C (O) N (R4j) R4k, -N (R4m) S (O) 2R3b, -S (O) 2N (R4n) (R4o), -S (O) 2R3c, -OS (O) 2R3d and / or aryl; R3a to R3d independently represent C1-6 alkyl; R4a and R4b independently represent H, C1-6 alkyl or together represent C3-6 alkylene, which results in a four to seven membered ring containing nitrogen; R4c to R4o independently represent Ho C1-6 alkyl; where each aryl group, unless otherwise specified, is optionally substituted; process comprising: a) (i) preparing a mixture solution of the compounds of formulas 1 and 2 in a solvent system comprising an aromatic hydrocarbon; (ii) co-crystallize the compounds of formulas 1 and 2 from that solution, whereby a mixture of crystalline material and mother liquor is produced; (iii) heating the resulting mixture to selectively dissolve the crystalline compound of formula 1 in the mother liquor; (iiii) separate the resulting solvent phase and crystalline product; and (iiiii) crystallize the compound of formula 1 contained in the solvent phase; or b) (i) preparing a mixture solution of the compounds of formulas 1 and 2 in a solvent system comprising a C2-6 alkyl alcohol; and (ii) crystallize the compound of formula 1 from that solution. Wherein the mixture of the compounds of formulas 1 and 2 can be prepared by reacting a compound of formula 3: R2-OH with a compound of formula (4), and wherein R1 and R2 have the meanings given in the claim 1, and L1 represents a leaving group.
