(4-fluoro-2-methylsulfonylphenyl)methanamine

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Methyl-5-(benzoyloxy)-2-{4-[(tert-butoxycarbonyl)amino]tetrahydro-2H-pyran-4-yl}-6-hydroxypyrimidine-4-carboxylate (C-30) in dry MeOH was treated with 4-fluoro-2-(methylsulfonyl)benzylamine (2.5 eq.) at reflux for 2 hours. Solvent was removed in vacuo and the residue was taken up in ethyl acetate, washed with HCl 1N, brine, dried over Na2SO4. The filtrate was concentrated in vacuo and triturated with ethyl ether to obtain the crude title compound (C-31). at reflux for 2 hours Solvent was removed in vacuo washed with HCl 1N, brine dried over Na2SO4 The filtrate was concentrated in vacuo triturated with ethyl ether

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
