実験手順

220 mg 4-chloro-2-[4-(4-chloro-phenyl)-piperazin-1-yl]-6,7-dihydro-thieno[3,2-d]pyrimidine 5-oxide (cf Example 124), 157.48 mg (R)-(−)-2-phenylglycinol and 197.52 μl diisopropylethylamine are placed in 4 ml dioxane, heated to 120° C. in the microwave for 0.3 hours. Then the reaction mixture is mixed with water, the precipitate formed is suction filtered, washed and dried. The diastereomers are separated by preparative HPLC (method B). 52.8 mg of Diastereomer 1 (Example 49) and 42.0 mg of Diastereomer 2 (Example 56) are obtained as a powder. 1H NMR (400 MHz, DMSO): Diastereomer 1: 7.41-7.35 (m, 2H), 7.35-7.28 (m, 2H), 7.28-7.19 (m, 3H), 6.99-6.92 (m, 2H); Diastereomer 2: 7.42-7.35 (m, 2H), 7.33-7.15 (m, 5H), 6.99-6.92 (m, 2H).
