Reaction Steps

To a solution of compound prepared in example 6 (250 mg, 0.60 mmoles) in DMF (2 mL), (tetrahydro-2H-pyran-4-yl)methanamine (138 mg, 1.20 mmoles), HOBT (121 mg, 0.90 mmoles), EDC.HCl (138 mg, 0.72 mmoles) and N-ethyl morpholine (227 μL, 1.80 mmoles) were added and reaction mixture was srirred at 25° C. for 2-5 hours under nitrogen atmosphere. The reaction mixture was poured into ice cold water and extracted with ethyl acetate. The combined ethyl acetate extract was washed with water & brine, dried over sodium sulphate and evaporated under reduced pressure. The crude product was triturated with hexane to yield 180 mg (49%) of product as white solid.
