5-[(R)-2-(2-{4-[4-(2-amino-2-methyl-propoxy)-phenylamino]-phenyl}-ethylamino)-1-hydroxy-ethyl]-8-hydroxy-1H-quinolin-2-one (0.21 g) was dissolved in a mixture of tetrahydrofuran (1.2 mL) and water (1.2 mL). 4-methyl cinnamic acid (0.07 g, predominantly trans) was added to the stirred solution at room temperature and it dissolved. After approximately 10 minutes, crystallisation occurred. The slurry was stirred overnight and filtered. The cake was washed with aqueous Tetrahydrofuran (1:1 THF:water, 2×0.4 mL, 1×0.2 mL) to afford the title compound which was dried overnight under vacuum at 45° C.
