PROCEDURE

实验过程

The reaction and after treatment of Example 8 are repeated, except that the trans-3-hydroxy-6-cyano-3,4-dihydro-2,2-dimethyl-4-(1,2-dihydro-2-oxo-4-t-butyldimethylsilyloxymethyl-1-pyridinyl)-2H-benzo[b]pyran used in Example 8 is replaced with the trans-3-hydroxy-6-trifluoromethyl-3,4-dihydro-2,2-dimethyl-4-(1,2-dihydro-2-oxo-4-t-butyldimethylsilyloxymethyl-1-pyridinyl)-2H-benzo[b]pyran obtained in Example 50. Thus, 6-trifluoromethyl-2,2-dimethyl-4-(1,2-dihydro-2-oxo-4-t-butyldimethylsilyloxymethyl-1-pyridinyl)-2H-benzo[b]pyran is obtained.
