DIPEA (4.1 mL) was added to a solution of 4,6-dichloropyrimidine-5-carbaldehyde (intermediate 8) (4.2 g) in DCM (85 mL) under an inert atmosphere. The solution was cooled to −10° C. and methylthioglycolate (2.1 mL) in DCM (40 mL) was added dropwise over 30 minutes. The reaction mixture was allowed to warm to ambient temperature over 2 hours, washed with water (4×50 mL), dried (MgSO4), filtered and concentrated in vacuo to give the title compound as an orange oil which later solidified (5.4 g, 92%);
