Procedure

In 40 ml of dichloromethane was dissolved 2.72 g of 2-methoxy-5-(5-trifluoromethyltetrazole-1-yl)benzaldehyde, and added thereto was 2.5 ml of 8 M methylamine in ethanol solution, 0.572 ml of acetic acid and 3.12 g of triacetoxy sodium borohydride, the mixture was stirred at room temperature for 6 hours. The reaction mixture was washed with saturated aqueous sodium hydrocarbonate solution, and the organic layers were dried and concentrate. The residue was purified by silica gel column chromatography (chloroform:methanol=49:1 to 4:1), to give 2.2 g of N-{2-methoxy-5-(5-trifluromethyltetrazole-1-yl)benzyl}-N-methylamine as shown in Table 136 below.
