Procedure

A stirred solution of 2-methoxy-6,7,8,9-tetrahydro-pyrido[1,2-a]indole-10-carboxaldehyde and ammonium acetate in nitroethane is heated to 100° C. for 1 h, cooled to room temperature and partitioned between ethyl acetate and water. The combined organic extracts are washed (water, brine), dried (sodium sulfate) and concentrated in vacuo to give the product.
