Participants

Reaction Steps

Tert-butyl 4-((2-chloro-7-methyl-4-morpholinothieno[3,2-d]pyrimidin-6-yl)methyl)piperazine-1-carboxylate (777 mg) was subjected to General Procedure E to give the HCl salt of 2-chloro-7-methyl-4-morpholino-6-((piperazin-1-yl)methyl)thieno[3,2-d]pyrimidine. The HCl salt of 2-chloro-7-methyl-4-morpholino-6-((piperazin-1-yl)methyl)thieno[3,2-d]pyrimidine (590 mg) was reacted with lactic acid via General Procedure B-2 to give (S)-1-(4-((2-chloro-7-methyl-4-morpholinothieno[3,2-d]pyrimidin-6-yl)methyl)piperazin-1-yl)-2-hydroxypropan-1-one.
