Procedure

7.2 g 2,4-dichloro-6,7-dihydro-thieno[3,2-d]pyrimidine (II) are placed in 36 ml dioxane, then 18 ml diisopropylethylamine and then 6.1 g (R)-(−)-2-amino-3-methyl-1-butanol are added. The reaction mixture is heated to 100° C. until there is no further reaction and after cooling it is evaporated down. The residue is treated with petroleum ether/ethyl acetate 9:1 in the ultrasound bath and the solid is suction filtered and dried. 8.3 g (III-2) are obtained as a solid. Analytical HPLC (method A): RT=2.75 min
