Procedure

To a solution of 2,4-dichloro-7-methyl-5,7-dihydrothieno[3,4-d]pyrimidine 6,6-dioxide (160 mg, 0.63 mmol), and triethylamine (64 mg, 0.63 mmol) in DMF (3 mL) at 0° C. was added 3-(S)-methylmorpholine (57 mg, 0.57 mmol). The resultant mixture was stirred at rt for 2 h. The solvent was removed under vacuum and the residue obtained partitioned between water and ethyl acetate. The organic layer was dried (Na2SO4) and concentrated to give the product which was purified by preparative TLC (petroleum ether/ethyl acetate=2/1) to produce 2-chloro-7-methyl-4-[(3S)-3-methylmorpholin-4-yl]-5,7-dihydrothieno[3,4-d]pyrimidine 6,6-dioxide (72 mg, 36% yield).
